ggspectra 0.3.7

Package documentation web site at: https://docs.r4photobiology.info/ggspectra/

The changes from version 0.3.6, the current CRAN release, are:

New

  • Track and profit from updated ‘photobiology’ (>= 0.10.4), with (>= 0.10.5) now required.
  • Use performance-optimized computation for colors from wavelengths.
  • Improve stat_wl_strip() performance by simplifying data before plotting.
  • Add support for plotting action spectra (preliminary).
  • Update y-axis scales to support scaled and normalized data.
  • Update y-scales to generate more compact axis labels and use IUPAC-recommended symbols.
  • Update x-axis- and y-axis scales to allow users to override the default label text.
  • Implement scale_y_Afr_continuous() for absorptance spectra.
  • Implement scale_y_mult_continuous() for calibration spectra.
  • Implement scale_y_Tfr_continuous() for transmittance spectra, to complement the internal and total versions earlier available.
  • Implement scale_y_A_continuous() for absorbance spectra, to complement the internal and total versions earlier available.
  • Implement scale_y_Rfr_continuous() for reflectance spectra, to complement the specular and total versions earlier available.
  • Update autoplot() methods to generate more compact axis labels (preliminary).
  • Update autoplot() methods to to natively support facets (partial).
  • Update stat_wb_box() adding parameter box.height (default behavior unchanged).

Bugs fixed

  • Fix a documentation example that stopped working because of changes to ‘ggplot2’.

Backward incompatibilities

  • Although this update should not break any code, the plots created will in some cases differ slighttly from those created with earlier versions. These changes affect the formatting of axis labels, and are readily visible.
  • Colors may differ very slightly while stat_wl_strip() draws fewer rectangles (in most cases these changes are barely visible).

NOTE: The updated package is on its way to CRAN.
