[R] .Rprofile under Windoze.

I am (for my sins) having to do some work using R under Windoze. I wanted to set up a .Rprofile to control my set-up. The docs on .Rprofile say that it can/should be placed in ``the user's home directory''. ``An Introduction to R'' observes lucidly that this concept needs to be clarified under Windoze.

Following the suggestions in An Introduction to R, I tried putting a .Rprofile in

        "C:\Documents and Settings\rolf\My Documents"

When that didn't work, I tried putting it in the starting directory (and confirmed that I'd got that right by checking with getwd() and list.files(all.files=TRUE) ).

The last invocation indicated that the name of the file was *really* ``.Rprofile.txt'' --- although I'd tried to save it as (simply) ``.Rprofile''. Is that the problem? If so, how can I persuade Windoze NOT to stick that damned .txt tag on the end? (Gawd, but I ***hate*** Windoze!!!) If that's not the problem, can you suggest what *is* the problem?

All that .Rprofile(.txt) has in it at the moment is

        options(prompt="Wheee! ")

so that I can easily tell whether it's working. If I execute

> source(".Rprofile.txt")

the prompt does indeed get changed to ``Wheee! '' as it should.

I would appreciate enlightenment. Ta.
