Multiple Checks on MEDITS Trawl Survey Data

Description

The function calls all the functions built in the package in an ordered way to perform a complete quality check of TX data available. The check is performed simultaneously on the files that can contain also data of more than one year.

Usage

RoME(TA,TB,TC,TE=NA,TL=NA,wd,suffix=NA,
create_RSufi_files = FALSE, create_global_RSufi_files=FALSE,
Year_start=NA,Year_end=NA,verbose =TRUE,Stratification=RoME::stratification_scheme,
Ref_list=RoME::TM_list,DataTargetSpecies=RoME::DataTargetSpecies,
Maturity=RoME::Maturity_parameters,
ab_parameters=RoME::LW,
stages_list=RoME::mat_stages,assTL=assTL)

Arguments

Details

RoME checks can be used to integrate a list of common quality checks on survey data. This function calls all the functions built in the package in an ordered way to perform a complete quality check of TX data available. The order of the checks in RoME was implemented in a defined sequence to avoid cascade errors due to the correction of a previous error. No automatic correction is implemented in 'RoME'. 'RoME' stops if an error occurs; then the user has to correct the error and run again the code to continue with the other checks. The function runs on a complete time series dataset, checking year after year, until the end of the time series. After the checks of the mandatory fields and the controlled vocabulary, that are carried out for all the TX tables, the specific checks on each kind of TX table are performed. Finally, RoME provides a list of cross checks aimed to guarantee the consistency among the data tables.

Some functions included in the 'RoME' library and used by RoME function need specific dictionaries or tables. It is the case of Stratification, Ref_list, DataTargetSpecies, Maturity_parameters, mat_stages and assTL tables. All of them are provided by default in this library. Anyway, the user has the possibility to provide ad hoc modified versions of these tables adapting the checks to specific needs.

Value

The function does not correct data, but it detects the errors, warning the user that there is the possibility of one or more errors, specifying the type of the error and easing the data correction. If parameter verbose=TRUE returns a series of text output in console to let the user to trace the state of the checks. All the output of the functions are stored in the user defined working directory wd and in the sub-directory there resident. In the Lofile subfolder are stored the logfiles of each run of the function.

Box-plots of swept-area-standardised abundance indices

Description

This function reads matching MEDITS TA (haul metadata) and TB (catch numbers) tables for a single survey year, computes the swept area for each haul, derives haul-level abundance indices expressed as individuals per km^2, and produces one or more box-plots that summarise the distribution of those indices by species. The plots are written to the folder ‘<wd>/Graphs/Abundance/’ and a logfile is produced under ‘<wd>/Logfiles/’ with a summary of any quality-control issues encountered.

Usage

check_abundance(ResultDataTA, ResultDataTB, year, wd,
suffix = NULL, distance_unit = "km", min_hauls = 5L)

Arguments

Details

A swept area is first computed for every haul from TA. The function then merges TA and TB. Hauls that lack swept area information or hauls whose total number of individuals is missing (or equal to zero when not allowed by the faunistic category) are discarded and reported in the logfile. Species occurring in fewer than min_hauls valid hauls are also removed. The remaining species are sorted alphabetically and divided into blocks of 36; one image file is produced for each block so that labels remain readable even in years with many species.

The function returns TRUE when no data-quality issues were found and FALSE otherwise.

Value

Logical scalar (TRUE if no errors, FALSE otherwise).

Author(s)

W. Zupa.

Examples

wd <- tempdir()
check_abundance(ResultDataTA = RoME::TA,
               ResultDataTB = RoME::TB,
               year = 2007,
               wd   = wd)

Check if TX files have the same area

Description

The function works with data of a single year of survey and checks if TX files have the same area code.

Usage

check_area(DataTA, DataTB, DataTC, DataTE=NA, DataTL=NA, year, wd, suffix)

Arguments

Details

TA, TB and TC tables are mandatory while TE and TL could be used where available.

Value

The function returns TRUE if no error occurs, while FALSE is returned when there are differences in the AREA code among the TX tables.

Check correctness of TL categories

Description

Check correctness of association between category and sub-category in TL consistent according to INSTRUCTION MANUAL VERSION 9

Usage

check_associations_category_TL(DataTL, assTL, year, wd, suffix)

Arguments

Details

The package uses a table of association between TL categories and sub-categories that is resident in the data folder of the package as assTL.rda file.

Value

The function returns always TRUE, because the outcome of the function is a warning that does not lock the execution of the 'RoME' checks. The presence of inconsistencies in the data is reported in the logfile stored in the "Logfiles"" subdirectory of the "wd"" user-defined directory.

check of bridles length correctness

Description

The function performs consistency checks of the values in the "BRIDLES_LENGTH" field of the hauls data table (TA).

Usage

check_bridles_length(DataTA, year, wd, suffix)

Arguments

Details

The field BRIDLES_LENGTH can assume value 100 between 10-200 m of depth or 150 between 200-800 m. The function highlights also that MEDITS handbook recommends to increase the bridle length to 200 m in depths deeper than 500 m, reporting a warning in the logfile. Empty (NA) records in "BRIDLES_LENGTH" will be eliminated being the presence of empty fields already checked by check_no_empty_fields

Value

The function returns always TRUE, because the outcome of the function is a warning that does not lock the execution of the 'RoME' checks. The presence of inconsistencies in the data is reported in the logfile stored in the "Logfiles"" subdirectory of the "wd"" user-defined directory.

Check of distance consistency

Description

The function checks whether there are inconsistencies between the DISTANCE field values in the TA table and the distances computed from the geographical coordinates of each haul.

Usage

check_distance(DataTA, year, wd, suffix)

Arguments

Details

The comparison between the DISTANCE field and the distance computed from shooting and hauling coordinates is performed with a tolerance threshold of 30%.

The geographic distance is calculated using the function distGeo() from the geosphere package, which computes the shortest path (great-circle distance) between two points on the Earth's ellipsoid (WGS84) using coordinates in decimal degrees.

Coordinates in the TA table are usually expressed in degrees and decimal minutes. These are automatically converted into decimal degrees using the internal function MEDITS.to.dd() before the computation.

Value

The function always returns TRUE. Its purpose is to generate warnings for hauls where the recorded DISTANCE differs significantly from the computed geographic distance.

Warnings are saved in a logfile located in the Logfiles subdirectory of the specified working directory. Additionally, for hauls with discrepancies, graphical maps are generated and saved in the Graphs subdirectory to support visual inspection and correction.

Check of length classes in TC

Description

The function checks the consistency of length classes in the TC table for the MEDITS survey. It verifies that the recorded length classes for each species fall within the expected ranges reported in a reference table of species-specific length limits. Warnings for inconsistencies are written to a CSV file for easier downstream analysis instead of being printed extensively in the log file.

Usage

check_length(DataTC, DataSpecies = NA, year, wd, suffix,
             DataTargetSpecies = RoME::DataTargetSpecies)

Arguments

Details

The function filters the TC data for the selected year and checks each length class recorded against the minimum (LMIN01) and maximum (LMAX99) length values defined for the corresponding species in the reference table. It also checks for negative or missing length class values. All detected issues are collected and saved in a CSV file for clear reporting, instead of generating verbose outputs in the log file.

Species with less than 50 observations in TC are excluded from the check by default, to focus the analysis on more frequently recorded species. The function ensures robust handling of missing (NA) values in both the TC table and the reference datasets to avoid false warnings.

A short summary of the check results is written to the .dat logfile. If no inconsistencies are detected, a message indicating successful validation is saved.

Value

Returns TRUE, invisibly. Detected inconsistencies are written to a CSV file in the working directory; if no issues are found, the CSV file remains empty apart from the header row.

Comprehensive consistency checks between MEDITS TB and TC files

Description

check_raising() performs a suite of integrity checks on a pair of MEDITS survey tables – TB (catch-at-haul) and TC (biological subsamples) – for one survey year. All inconsistencies are written to a plain-text logfile; the routine never stops at the first error, so you always get the full list of issues detected.

Usage

check_raising(ResultDataTB, ResultDataTC, year, wd, suffix = NULL)

Arguments

Details

The function executes five independent validations:

1. Weight consistency – When more than one subsample exists for a given haul/species in TC, the sum of WEIGHT_OF_THE_FRACTION must equal TOTAL_WEIGHT_IN_THE_HAUL recorded in TB.

2. Raising factor – For each subsample the ratio molt given by WEIGHT_OF_THE_FRACTION / WEIGHT_OF_THE_SAMPLE_MEASURED must be \ge 1.

3. Sex-specific numbers – For every combination haul * species * sex the raised total of individuals in TC must match TB columns NB_OF_FEMALES, NB_OF_MALES or NB_OF_UNDETERMINED.

4. Total individuals (TC -> TB) – For every haul/species the sum of raised numbers across all sexes in TC must equal TOTAL_NUMBER_IN_THE_HAUL in TB. This catches cases where an entire sex is missing from TC.

5. Internal TB consistency – Within TB the sum of the three sex-specific columns must equal TOTAL_NUMBER_IN_THE_HAUL for each haul/species.

If any of these checks fails, an explanatory line is appended to the logfile ‘Logfiles/Logfile_.dat’. The function finally returns a single logical value: TRUE when no errors are detected, FALSE otherwise.

Tidy-evaluation is used inside the dplyr pipelines; the following symbols are declared in globalVariables to avoid "no visible binding" notes during R CMD check: COUNTRY, YEAR, HAUL_NUMBER, GENUS, SPECIES, WEIGHT_OF_THE_FRACTION, WEIGHT_OF_THE_SAMPLE_MEASURED, NUMBER_OF_INDIVIDUALS_IN_THE_LENGTH_CLASS_AND_MATURITY_STAGE, SEX, NB_OF_FEMALES, NB_OF_MALES, NB_OF_UNDETERMINED, TOTAL_WEIGHT_IN_THE_HAUL, TOTAL_NUMBER_IN_THE_HAUL, codedsex, N, molt, raised, RaisedSex, RaisedTotal, n_subsamples, total_fraction, SumSexTB.

Value

Logical scalar: TRUE if the dataset passes all checks, FALSE otherwise.

Usage

check_rubincode(ResultData,year,TMlist,wd,suffix)

Arguments

Details

The checks execution is stopped if any mismatching record was found.

Value

The function returns always TRUE if used to check TB tables, indicating in the logfile the species codes not present in TM list. If unexpected rubin codes are detected in both TC and TE tables an error (FALSE value) is reported in the logfile, interrupting the function running.

Check for mature individuals below literature thresholds in TC data

Description

This function verifies the consistency of maturity information in TC data by detecting mature individuals whose lengths are smaller than the smallest mature size reported in the literature for each species and sex. Detected inconsistencies are saved in a CSV file for traceability and further review, while a concise summary is written in the log file.

Usage

check_smallest_mature(ResultData, year, MaturityParameters, TargetSpecies,
  wd, suffix)

Arguments

Details

The function processes the TC data for the selected year and examines each species listed in the MaturityParameters table. For each mature individual (i.e.\ not coded as immature stages), it checks whether the length class is smaller than the bibliographic minimum threshold, allowing a 10% tolerance buffer to account for biological variability. If such individuals are detected, they are recorded in a CSV file including:

• GSA

• Year

• Species

• Sex

• Haul number

• Length class (mm)

• Threshold applied (mm)

• Literature threshold (mm)

• Bibliographic reference

• Type of file

• Type of warning

A concise message summarizing how many records were written to the CSV is printed to the log file (.dat). If no inconsistencies are found, the function logs a message indicating that all maturity stages are above bibliographic thresholds.

The check uses the updated DataTargetSpecies table for consistency with current species definitions and codes.

Value

The function always returns TRUE. Its purpose is to perform quality checks and log potential issues, but it does not interrupt the execution of other routines in the RoME package.

Check consistency of maturity stages with respect to the spawning period

Description

This function checks whether maturity stages reported in TC (or TE) are consistent with the reproductive period of each species. It detects three situations:

• Immature individuals caught during the spawning period but with lengths above the bibliographic threshold (maximum L50 plus 20%).

• Mature individuals caught outside the spawning period.

• Mature individuals caught outside the spawning period and with lengths smaller than the smallest mature individual reported in the literature.

The check uses bibliographic information from the Maturity_parameters table, including L50 values and spawning months.

Usage

check_spawning_period(ResultDataTA, ResultDataTC, year,
Maturity_parameters, DataTargetSpecies, wd, suffix)

Arguments

Details

The function reads information from Maturity_parameters to identify the reproductive period (spawning season) of each species and sex. It then compares each record in TC or TE with these periods:

• Immature individuals (maturity codes 0, 1, 2A) are flagged if they are captured during the spawning period and have lengths exceeding the bibliographic threshold (maximum L50 + 20%).

• Mature individuals are checked to verify whether they were caught outside the defined spawning period.

• Among mature individuals outside the spawning period, those with lengths smaller than the smallest mature specimen reported in literature are additionally flagged.

Warnings are written both to a .dat logfile and to a CSV file for easier downstream analysis. The CSV output includes details on GSA, year, haul number, species, sex, length class, spawning period months, month of capture, and type of warning.

Value

The function always returns TRUE, as it is designed to produce warnings rather than halt execution of further routines in the RoME package.

Check Swept Area Calculation and Plot

Description

Performs data validation and swept area calculation for MEDITS TA-format data. The function verifies numeric consistency in key columns, computes mean depth and swept area, logs any detected issues, and generates a plot of swept area versus mean depth for visual inspection.

Usage

check_swept_area(ResultDataTA, year, wd, suffix)

Arguments

Details

This function performs multiple validation steps on TA-format data for MEDITS hauls. It verifies that certain key columns contain numeric values and checks for missing or empty entries in critical fields such as WING_OPENING and DISTANCE.

For each haul, it calculates the mean depth as the average of SHOOTING_DEPTH and HAULING_DEPTH, and estimates the swept area in square kilometers using the formula (WING\_OPENING / 10) \times DISTANCE / 10^6. Any inconsistencies or errors encountered during these checks are written to a logfile stored in the Logfiles folder. If the data contains valid entries, the function generates and saves a scatter plot showing the swept area against mean depth. The plot includes a background shading to visually separate the depth range 0-200 meters from deeper strata, assisting in the interpretation of data distribution across depth zones. All output files are organized within subfolders named Logfiles and Graphs under the specified working directory.

Value

A logical value:

• TRUE if no errors were detected in the data.

• FALSE if at least one error was found and logged.

# Run the check for year 2005
check_swept_area(ResultDataTA, year = 2005, wd = wd, suffix = NULL)

Function to check the consistency of the temperature data stored in haul data table (TA).

Description

This function checks if the temperature by haul is in the range 10-30 Celsius degrees; moreover, a plot depth versus temperature is produced and stored in the Graph folder.

Usage

check_temperature(ResultDataTA,year,wd,suffix)

Arguments

Details

This check uses the temperature range 10-30 Celsius degrees to provide quantitative warning and a plot, automatically stored in Graphs, for a qualitative inspection of that temperature data respect to depth.

Value

The function returns always TRUE, because the outcome of the function is a warning that does not lock the execution of the 'RoME' checks. The presence of inconsistencies in the data is reported in the logfile stored in the "Logfiles" subdirectory of the "wd" user-defined directory.

Check consistency between total weight and number of individuals in MEDITS TB data.

Description

This function performs quality checks on the consistency between the total weight and the total number of individuals recorded in the MEDITS TB table. The consistency check is carried out both quantitatively-using known reference ranges of mean weights for each species-and qualitatively-via plots displaying the observed mean weights for each species across hauls.

Usage

  check_weight(ResultDataTB, year, DataTargetSpecies, wd, suffix)

Arguments

Details

The function operates in two phases:

1. Quantitative Check:

• For each record in the TB table, the mean individual weight is computed.

• If the species is listed in DataTargetSpecies, the mean weight is compared to its 5th-95th percentile reference range.

• If the mean weight falls outside this interval, a record is saved in a CSV file reporting:

  • GSA

  • Year

  • Species

  • Haul number

  • Observed mean weight

  • Reference minimum (5th percentile)

  • Reference maximum (95th percentile)

  • Type of file

2. Qualitative Check (Plots):

• For all species present in the dataset, the function generates plots of mean weight by haul, to visually check for possible outliers or abnormal variability.

• To avoid excessive plotting, only species with at least 5 observations are plotted.

• Plots display the mean weight for each haul, with haul numbers shown as labels.

• If many species qualify for plotting, the function automatically splits the plots into multiple pages, each saved as a separate JPEG file. Each JPEG file contains up to 6 plots.

Files Produced:

• Logfile (.dat): Contains a short message summarising whether any outliers were detected. Detailed warnings are no longer written here but are instead stored in the CSV file.

• CSV File: Named as Check_Mean_Weights_Logfile_GSA<AREA>_Year<YEAR>_<suffix>.csv. Contains all observations where the mean weight falls outside the expected reference range.

• Plots: Saved in JPEG format in the Graphs subdirectory. Filenames include GSA, year, and a page number.

Value

This function always returns TRUE. The purpose of the function is to perform checks and report inconsistencies, but it does not interrupt the execution of other routines in the RoME package.
