That's a bug in 2.13.0 which has been fixed in R-patched.  The easiest 
thing is probably to install R-patched (binary builds are on CRAN); 
another workaround (which will cause you headaches in the future, so I 
don't really recommend it) is to define the environment variable R_HOME 
set equal to the path to the R home directory in Windows format with 
backslashes.  (The headaches come when you upgrade and it points to the 
wrong place.)

The paths need to contain backslashes in 2.13.0.  R-patched will be 
happy with the forward slashes you used.
