Release CRAN version 2.2.0 · rmaia/pavo

NEW FEATURES AND SIGNIFICANT CHANGES

added k-medoids clustering as an option in classify()
coldist() now returns unweighted Euclidean distances for generic di-, tri-, and tetra-chromatic colspace() models. Users wishing to estimate noise-weighted distances (i.e. via the receptor-noise limited model) should continue to use coldist() directly on vismodel() objects, as previously.

added a message to indicate what distance metric is being calculated during calls to coldist()
vismodel(), colspace(), and coldist() now always return lum and dL columns, for consistency
irrad2flux() and flux2irrad() use slightly more precise constant values, which may lead to slightly different results (less than 0.1% difference between this new version and the previous versions)
getimg() can now import images from URL's
the cores argument in getimg() is deprecated, as image import is vectorised
fixed a small bug in classify() when using refID and kcols for multiple images
the resize argument in procimg() now takes a percentage, rather than scaling factor
fixed a bug where colspace(space = segment) would return both a B and (redundant) lum column
fixed a bug where the rod sensitivity of Canis familiaris was inaccessible through vismodel()
fixed an issue in getspec() where badly encoded characters in some spectral files would cause failure
fixed a bug where coldist() would attempt to estimate receptor-noise weigted distances rather than cie-distances for cielch model results
