[R] Error installing packages

[Kevin E. Thorpe]

Hello.

I am posting this on behalf of one of my students who is getting error 
messages when installing some packages. I have not seen this before nor 
have I been able to replicate it. I'm including the relevant (I think) 
information. I get the students to install rms with dependencies. As you 
can see, rms does get installed but when the attempt is made to attach 
it, ggplot2 cannot be loaded. Thus I tried explicitly installing ggplot2 
and you can see then ensuing errors below. I have included the 
sessionInfo() at the end.

I hope someone can point me at a solution.
