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.
