The main changes from version 0.4.23 the previous CRAN release, are:

  • Replace use of deprecated tidyr::gather_().
  • Add function read_cid_spectravue_csv() supporting data import from measurements CSV files output by CID Bio-Science’s SpectraVue CI-710s leaf spectrometer.
  • Add function read_foreign2mspct() to apply an import function to a list of files.
  • Add color-related functions spct_CRI(), spct_CCT() and expect_SSI() implemented as wrappers to functions in package ‘colorSpec’. These functions accept source_spct objects as arguments. CRI, CCT and SSI are quantities used to describe light used for illumination, photography, cinematography and video.
