ggspectra 0.3.9

ggspectra 0.3.8

This update brings many improvements to autoplot() methods. These include enhanced capabilities for handling of normalized and scaled spectral data, as well as cosmetic tweaks to labels. It also tracks changes in packages ‘ggrepel’ (>= 0.9.1), ‘photobiology’ (>= 0.10.10) and ‘ggplot2’ (>= 3.3.3) and deprecation of functions in ‘tidyr’ (>= 1.0.0). The updated code depends on the revised normalize() function in ‘photobiology’ (>= 0.10.10) and on ‘ggrepel’ (>= 0.9.1).

ggspectra 0.3.7

ggspectra 0.3.6

Although this update should not break any code, the plots created will in many cases differ from those created with earlier versions. Changes only affect the text of labels.

ggspectra 0.3.5

ggspectra 0.3.4

ggspectra 0.3.3-1

ggspectra 0.3.2

ggspectra 0.3.1

ggspectra 0.3.0

Change the names of some the values calculated by the stats defined in ‘ggspectra’ to avoid confusion with the names of ‘ggplot2’ aesthetics. This is a code breaking change!

Revise to track changes in ‘photobiology’ version 0.9.24 and ‘ggplot2’ 3.0.0, which are now required.

ggspectra 0.2.4

Revise to track changes in ‘photobiology’ 0.9.20 to avoid spurious messages.

ggspectra 0.2.3

Track changes in package ‘photobiology’ 0.9.18.

Improve handling of plot titles.

ggspectra 0.2.2

Track changes in package ‘photobiology’ 0.9.16 and 0.9.17. This among other improvements makes it easy to plot spectral absorptance. Expand y scale to expected range in all cases, but do not force these limits in any case when data exceeds them, except for absorbance for which the y scale is not expanded past 6 a.u. Add new annotation "boundaries" to highlight with horizontal line(s) the expected range of the plotted quantity, highlighting the limit(s) exceeded if data fall outside the expected/range. Add previously missing ggplot() method for class object_spct. Revise vignettes.

ggspectra 0.2.1

Track changes in package ‘photobiology’ 0.9.14. Add continuous scales with defaults suitable for spectral data, with support for automatic axis labels both as R-expressions and as LaTeX mark-up. Add utility functions for SI scale prefixes. Add utility functions for x-axis-labels and secondary x-axis. Add utility functions for y-axis-labels. Update User Guide (add examples of graphical comparison of multiple lists of wavebands).

ggspectra 0.2.0

Improve handling of annotations parameter in plot() methods. Add functions ggcolorchart() and black_or_white(). Add statistics stat_wb_box() and stat_wb_column() with "rect" as default geom and stat_wb_hbar() with "errorbarh" as default geom. Change default geom from "rect" to "text" in all the summary stats for spectra. Update stats with “text” as default geom to use an additional variable BW.color computed by black_or_white() as default mapping for color. As default geoms and color mapping have changed, this update can break existing code. Changes to plot() methods are backwards compatible but default color of some text labels is changed from "white" to "black" to improve readability, and fewer peaks and valleys are highlighted by default. In addition more ticks marks are used on the wavelength axis. Fix minor bugs in handling of color mapping. Update documentation.

ggspectra 0.1.12

Import ‘ggplot2’ in whole as only the most basic use of plot() methods would not require user access to ‘ggplot2’. Add stat_label_peaks() and stat_label_valleys() which are designed to fully take advantage of geom_text_repel() and geom_label_repel() as revised in package ‘ggrepel’ (>= 0.6.3). Change behaviour of plot() methods so that “illegal” values such as negative spectral irradiances or transmittances are plotted by default. Fix several minor bugs affecting plot() methods with certain non-default sets of annotations. Improve documentation and vignettes.

ggspectra 0.1.11

ggspectra 0.1.10

Add code to maintain same stacking order under ‘ggplot2’ 1.1.0, 2.0.0, 2.1.0, and 2.1.9000 in plot.object_spct().

ggspectra 0.1.9

Add support for na.rm to all plot() methods setting default to TRUE, and avoid triggering spurious warnings from internal code. Make default for parameter label.qty in plot methods dependent on whether data are expressed in absolute units or have been rescaled or normalized. Move from the ‘User Guide’ the sections on plot() methods creating a new vignette titled ‘Plot Methods’.

ggspectra 0.1.8

Add support for plot.qty = "absorptance" to plot.filter_spct(). Add support for plot.qty to plot.object_spct() with possible values: "all" or NULL (previous behaviour, and current default), "transmittance", "absorbance", "absorptance", and "reflectance". The new options plot only one quantity at a time as a line instead of the default area plot.

ggspectra 0.1.7

Add stat_wb_label(), stat_wb_e_irrad(), stat_wb_q_irrad(), stat_wb_e_sirrad(), and stat_wb_q_irrad(). Revise plot.raw_spct() to handle multiple "counts" columns. Revise plot.cps_spct() to handle multiple "cps" columns. Add text.size parameter to all plot() methods. Can be used to control the size of the font used for text decorations related to wavebands, peaks and valleys. Increase slightly the default font size for plot decorations, and decrease the number of peaks and valleys labelled by the plot() methods. Fix existing bug revealed by dplyr update. Fix bug in decoration() affecting plot.object_spct(). Fix other minor bugs.

ggspectra 0.1.6

(First CRAN release)

Clean documentation and code for CRAN submission. Add examples of plotting of waveband objects as these were removed from the vignette of package ‘photobiologyWavebands’.

ggspectra 0.1.5

Fix bug in documentation.

ggspectra 0.1.4

Improve documentation.

ggspectra 0.1.3

Remove wb_guide(). Remove wb_wb_summary(). Add stat_wb_mean(), stat_wb_total(), stat_wb_contribution(), stat_wb_relative(). Add stat_wb_irrad(), stat_wb_sirrad()

Implement 100% of the old functionality of the plot() methods, but without using any annotations. In other words, now all calculations work as expected with grouping and panels. Some aesthetics may require tweaking in the case of grouping.

Tested with packages ‘ggrepel’ and ‘cowplot’.

ggspectra 0.1.2

Add text explaining examples to User Guide.

Rename several stats and functions with more descriptive names.

stat_color_guide() -> stat_wl_strip()

stat_average() -> stat_wl_summary()

stat_waveband() -> stat_wb_summary()

color_guide() -> wl_guide()

waveband_guide() -> wb_guide()

ggspectra 0.1.1

Add multiplot() function (unchanged from package photobiologygg). Improve stat_waveband(). Add color_guide(), waveband_guide().

Add ggplot() methods for spectra, which use default mappings if mapping not explicitly supplied as argument to call.

Make plot() methods almost fully functional. "contribution" and "participation" summary values not yet implemented. Neither summaries for BSWFs. If requested these summaries will show as NaN (not a number) in the plots.

ggspectra 0.1.0

First preview version. Still with incomplete functionality.
