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.

Indeed, the path is missing, though it was there when I issued the
update.packages command.
