.Rprofile in 1.3.1 (os 10.1)

to anyone interested in creating an .Rprofile file in os X:

	After having some problems getting the .Rprofile file to work in
under 10.1 I have discovered the following:

1) OS 10.1 doesn't let you name files that begin with a period '.' in 
the
Finder, or save them in programs such as BBedit. The only way to 
create a
file that begins with a period is to use the command line. (i.e. use
Terminal, and use the mv command: "mv filename .filename")

2) R 1.3.1 carbon for mac OS 10/9 requires that the line breaks be
Macintosh line breaks and not Unix line breaks. Thus, a file such as
..Rprofile created and saved using pico will not work, as the line 
breaks
are unix and not mac.

	Thus, in order to create a working .Rprofile command I had to
first create a file with mac line breaks in BBedit, and save it as
"Rprofile", and then use the Terminal to change the name:
"mv Rprofile .Rprofile"

hope this helps someone avoid some frustration,
