im using plclust and want the labels to be different colors.
i took a look at getS3method("plot","hclust")
and saw a call to .Internal. i looked at the help on .Internal and dont
know where to go next. any help appreciated!
thanks,
rafael

In your case the lines {"dend", do_dend, 0, 111, 6, {PP_FUNCALL, PREC_FN, 0}}, {"dend.window", do_dendwindow, 0, 111, 5, {PP_FUNCALL, PREC_FN, 0}}, and gannet% grep do_dend *.c ... plot.c:SEXP do_dend(SEXP call, SEXP op, SEXP args, SEXP env) plot.c:SEXP do_dendwindow(SEXP call, SEXP op, SEXP args, SEXP env) (This might be better continued on R-devel, if it need continuing.) -- Brian D.

Just a few days ago, there was a question with almost identical content (though different wording). Please see in the archives for my answer with Subject 'Re: [R] Customizing Cluster Analysis plots created with hclust' Short answer: It will be possible in "R-devel" via as.dendrogram(..)
