raster_to_array

Recreates the original numeric array from a <code>raster</code> object created
by <a href="/link/grDevices%3A%3Aas.raster?package=recolorize&version=0.2.0" data-mini-rdoc="recolorize::grDevices::as.raster">grDevices::as.raster</a>. Not to be confused with the <code>Raster*</code> classes
used by the <code>raster</code> package.

Automatic, semi-automatic, and manual functions for
generating color maps from images. The idea is to simplify
the colors of an image according to a metric that is useful for
the user, using deterministic methods whenever possible.
Many images will be clustered well using the out-of-the-box
functions, but the package also includes a toolbox of functions
for making manual adjustments (layer merging/isolation, blurring,
fitting to provided color clusters or those from another image, etc).
Also includes export methods for other color/pattern analysis packages
(pavo, patternize, colordistance).
