photobiology 0.10.11

This update adds flexibility to the user interface used to indicate the target when searching for wavelengths matching specific spectral data values. It also contains a preliminary implementation of classes solute_spct and collections solute_mspct for storing spectral molar or mass coefficients of attenuation.

Changes from version 0.10.10 the most recent CRAN release, are:

  • Add new classes of objects solute_spct and solute_mspct to be used to store molar (default) and mass based coefficients of attenuation describing overall attenuation, or attenuation by absorption or by scattering. Implement the corresponding methods. (Unstable: interface may change).
  • Add example data for two substances: water.spct and phenylalanine.spct.
  • Rewrite join_mspct() to use interpolation when wavelengths differ among member spectra. This should not break old code but output can slightly differ.
  • Expand syntax accepted for character arguments passed to parameter target in all wls_at_target() methods and function find_wls().
  • Fix failure to correctly handle spectra with zero rows, a bug affecting several methods, operators and functions including rbindspct() and find_wls().
  • Fix bug in rowwise_filter() affecting parallel summaries of absorptance.
  • Fix bugs in extraction and replacement functions for collections of spectra, possibly triggered by changes in R >= 4.0.0.
  • Add method s_mean_se_band_band().

The package documentation web site is at https://docs.r4photobiology.info/photobiology/ includes a changelog with information for each release since version 0.1.0.

NOTE: Version 0.10.11 has been submitted to CRAN.
