> install.packages("Hmisc", dependencies=TRUE)
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
  package ‘Hmisc’ is not available

Error in library(Hmisc) : there is no package called 'Hmisc'

I am running Mac OS X Snow Leopard latest version and also have the latest R UI for Mac.

How can Hmisc be installed manually?
