Internal function. A utility function which looks for gr.crit in the file names of .csv
files and assigns group membership. Also assigns a color,
and for Spectra objects, a symbol and an
alternate symbol to each group. Warnings are given if there are file names
that don't match entries in gr.crit or there are entries in
gr.crit that don't match any file names. An internal function, not
generally called by the user.
.groupNcolor(spectra, gr.crit = NULL, gr.cols = "auto", mode = "1D")A complete object of S3 class Spectra or Spectra2D. This
function is the last internal step in creating these objects.
Until this function has done its job, these objects
will not pass checks as the assembly is not complete
(see chkSpectra).
An object of S3 class ChemoSpec::Spectra() or ChemoSpec2D::Spectra2D().
