If TRUE, labels 0 will be assigned color grey. Otherwise, labels below 1 will trigger
an error.
colorSeq
Color sequence corresponding to labels. If not given, a standard sequence will be
used.
Value
A vector or array of character strings of the same length or dimensions as labels.
Details
The standard sequence start with well-distinguishable colors, and after about 40 turns into a
quasi-random sampling of all colors available in R with the exception of all shades of grey (and gray).
If the input labels have a dimension attribute, it is copied into the output, meaning the
dimensions of the returned value are the same as those of the input labels.
