Hi,

My R version is 2.4.1 and I installed the the packages MASS and run
command library("MASS"),

however when I type ?rmvnorm, no help topic found, it worked before.

I tried to ype ?rinvgamma from "MCMCpack" which works great.

Anybody have idea? I also reinstalled MASS package, but when I try to type
rmvnorm(), no functions found.
