Hi,

My student and I installed R on our respective macs in a different way  
and the package version numbers that are offered to us using the  
Package Installer menu command are different.

My student did an installed of 2.9.1 using the installer found at <http://cran.r-project.org/ 
 > for Tiger and Leopard.

Because I thought I'd give a try to the 64-bit version, I instead went  
to <http://R.research.att.com/> and first downloaded and installed the  
R2.9.0 package for Leopard (32 and 64 bit), and then the 2.9.1 patched  
version which I copied on top of the old version (thus replacing it).

I also downloaded the latest R gui. Upon starting R I get

R version 2.9.1 Patched (2009-07-16 r48939)

But the Package installer tells my the latest version of plyr is  
0.1.5, whereas for my student, the latest version of plyr is 0.1.9.

Is this because plyr 0.1.9 is not available in 64-bit yet?
