Windows XP.  I have just updated to R 2.11.0 and then run

Is that a cut and paste of the error message?  Normally R would double 
the backslashes when displaying a string, so it looks as though you've 
somehow got a path containing the control characters \P, \R, and \L.  >Did 

you set the lib.loc argument when you called update.packages?

Thank you!  Yes, it's cut and paste.

I did not set lib.loc in the

call (made through the Rgui.exe menu system), but I have the library
location defined in the environment:

R_LIBS=c:/Program Files/R/Library

I've been using this approach for several years, and it's worked
without problem until now.

I can't seem to reproduce this.  If it happens reproducibly on your system, 
could you please do the following:
print the result of installed.packages()["PBSmodelling",], .libPaths() and 
sessionInfo()?

A possible workaround is to get the names of all of your packages in the 
Library folder and install them, rather than using the update.packages() 
function.  This may fail if some of them aren't on CRAN or the other 
repositories.
