Release CRAN version 2.3.0 · rmaia/pavo

NEW FEATURES AND SIGNIFICANT CHANGES

plot.rspec() now adds a linear spectrum alongside the x-axis to show the
hues corresponding to each wavelength (controlled by the wl.guide boolean
argument).
cieplot() (and therefore plot.colspace() for CIEXYZ model) now adds the
background of the CIEXYZ colour space by default. This can be turned off by
switching the ciebg argument to FALSE.
voloverlap() uses a different algorithm to determine volume overlaps, which
means:
- computation is now much more efficient
- voloverlap() now works for trispace() objects as well
- accordingly, first two arguments of voloverlap() has been renamed colsp1
  and colsp2 instead of tcsres1 and tcsres2
- slow and possibly inaccurate montecarlo option has been deprecated

errors during argument checks in vismodel() now have more explicit messages.
all pavo functions (excepted vismodel() and spec2rgb()) now work with
sub-nm precision, for rspec objects with non-integer wavelengths.
summary.colspace() no longer fails for tcs objects with only one row.
vismodel() now works for monochromats as well.
procspec(opt = "bin") no longer counts bin edges twice (once in each consecutive bin). This will cause changes in the bin stops compared to earlier versions of this function.
coc() and categorical() spaces now return Weber luminance contrast by default when passed through coldist(), rather than nothing (as per the original publications).
coldist() can now take multiple values for weber, when Weber fractions are known for all receptor classes
summary.rspec() no longer errors for a single spectrum when the wavelength range does not contain 450-700nm
