Multiple comparisons in R; multicomp

There is now a package in R called multcomp for general multiple
comparisons that does things similar to the Splus library you mentioned.
BTW, a search of the help archives for multicomp or "multiple
comparisons" brings this up.

HTH, Andy

I'm not familiar with the multcomp package from s-plus, but there is a
package available through bioconductor (www.bioconductor.org) called
multtest that has some functions for multiple testing procedures and
adjusting p-values and computing false discovery rates.
