I did something a little bit different, however the dim() was what needed I
think. Here is the code
col=rainbow( if(is.matrix(rk.temp.x)) dim(rk.temp.x) else rk.temp.x)

Since the only problem was with matrix, that fixes it. For summary of factor
variables both length(rk.temp.x) and rk.temp.x work correctly. However with
simple vectors the length(rk.temp.x) does not work correctly giving one
color per value. So I prfered the simple rk.temp.x. I send a pdf with
example plots to take a look. I think it is ok now. I will commit it to svn
in few minutes.

Not much time to experiment with it, however. You may have to try some
