Hopefully a simple question. I installed "RColorBrewer" as a package.
It works fine in R, but I can't invoke it properly in RPy.
In R, it's invoked as "brewer.xxx", but "r.brewer" is not found
by python.
It'd be nice if the examples had a library call (I think the faithful
one has two library calls but both are obsolete and are part of stats
now).
RPy 1.0RC2, R 2.5.0.
