Thank you for your suggestion however I could not give it a try since landed in the same  issue being reported about the Hmisc package:

> 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'

+ "blue", geom = "errorbar")
Error: Hmisc package required for this functionality.  Please install and try again.

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?

Best regards,
