[R] Trouble loading package

I am trying to load a package called Rmark, but when I run 


I get the following:

> library(RMark)
Error in !character.only : invalid argument type
Error in library(RMark) : .First.lib failed for 'RMark'

When I try to load Rmark from the packages menu, I get:

> local({pkg <- select.list(sort(.packages(all.available = TRUE)))
+ if(nchar(pkg)) library(pkg, character.only=TRUE)})
Error in !character.only : invalid argument type
Error in library(pkg, character.only = TRUE) : 
  .First.lib failed for 'RMark'

Any ideas what is causing this error?

My OS is Windows XP, and my R version is R.2.10.1
