Cleanup Old GeyserTimes Data Files

Description

Removes a particular version of the GeyserTimes data files that have been download and stored on disk by gt_get_data. Alternatively, the function will remove all old versions of the GeyserTimes data files, keeping only the most recent files.

Usage

gt_cleanup_data(version = NULL, old = FALSE, path = gt_path())

Arguments

version

a character value, the specific version of the GeyserTimes data files to be removed. The version number is the date that the files were downloaded, with the format yyyy-m-d e.g. "2021-05-15".

old

a logical value, if TRUE, all but the most recent version of the data files found under path will be removed.

path

a character value, the location on disk where the GeyserTimes data files.

Details

Users who regularly download the latest GeysersTimes data may want to call gt_cleanup_data(old=TRUE) to clean out old copies of the data.

Value

a character vector, the versions of the data files that were removed. If no files are removed, NULL is returned.

Download GeyserTimes Data

Description

Downloads the data from geysertimes.org. Reads the data and creates a tibble object in 'dest_folder'.

Usage

gt_get_data(dest_folder = file.path(tempdir(), "geysertimes"),
  overwrite = FALSE, quiet = FALSE, version = lubridate::today())

Arguments

dest_folder

the location where the binary tibble object should be written. The default is under the current R session's temp directory which will disappear when the session ends.

overwrite

a logical value, ifFALSE, the data will not be downloaded again if copy of the data, with version, already exists in dest_folder.

quiet

a logical value, if TRUE, no messages are displayed.

version

a character string giving the version of the data to download. This should a date in the form yyyy-mm-dd. Typically, only the version with today's date is available.

Details

The data is downloaded from the GeyserTimes archive web site https://geysertimes.org/archive/ to the tempdir() directory. The data is then read with readr::read_tsv with appropriate column types. The resulting tibble object is then saved as an binary (.rds) in dest_folder.

Value

a character string giving the full path to the directory where the GeyserTimes data was stored.

Note

Users are encouraged to set dest_folder to gt_path() to save a persistent copy of the data.

Examples

dpath1 <- gt_get_data(dest=gt_path())  # data saved under gt_path()
gt_cleanup_data(gt_version())

Load the Geyser Times Data

Description

Loads the Geyser Times data that was previously downloaded by a call to gt_get_data.

Usage

gt_load_eruptions(path = gt_path(), quiet = FALSE, version = NULL)
gt_load_geysers(path = gt_path(), quiet = FALSE, version = NULL)

Arguments

path

a character string, the local location where the Geyser Times data has been written. The default is the local permanent location given by gt_path(). If no appropriate data is found at that location, the function will look in the temporary location given by gt_path(temp=TRUE).

quiet

a logical value, if TRUE, no messages are displayed.

version

a character string giving the version of the Geyser Times data to load. Calling gt_version(path, all=TRUE) will list all versions available under path.

Details

Typically, a user would download the data once, with a call to 'gt_get_data(destdir=gt_path())'. Subsequent R sessions can the load this downloaded data with a call to 'gt_load_eruptions()'.

Value

a tibble containing the Geyser Times data with names: (need to decide on appropriate names)

Path to GeyserTimes Local Data

Description

Returns the path where local GeyserTimes data is stored.

Usage

gt_path(temp = FALSE)

Arguments

temp

a logical value, if TRUE, the temporary path is returned. This location will disappear when the R session ends.

Value

a character string giving the full path where local GeyserTimes data is stored.

Note

Prior to version 0.1.8, the geysertimes package used a location specified by rappdirs::user_data_dir for storing local GeyserTimes data. Starting with version 0.1.8, the package now uses the location tools::R_user_dir("geysertimes", "data").

Version of GeyserTimes Data

Description

Returns the version of the current GeyserTimes data. This is a character string date in year-mm-dy format.

Usage

gt_version(path = gt_path(), quiet = FALSE, all = FALSE)

Arguments

path

the path to the GeyserTimes data. The default is the suggested location used by 'gt_get_data'.

quiet

a logical value, if TRUE, no messages are printed.
