[R] Setting up a .Rprofile file

[Bruce Ratner PhD]

Henrico:
Thanks for quick reply.
However, one last question:
If I want to change working directory, and put setwd() in the Rprofile file, logically R will not know where the be work directory is, correct?

So, should I install R in my preferred working directory?

Thanks again, in advance. 
Bruce
