different .Rprofile files for different projects

Dear list, First off, let me offer my apologies, I know this is a very basic question. After amassing a large number of objects (from multiple projects) in one working directory, I'd like to be able to start using different directories, just for the sake of organization alone. But I have no idea how to do this. I am using a mac, running R 2.5.
I'm not very familiar with the MacOS X version of R, but students of mine were using it recently and under the Misc menu there is an entry to change the working directory, which provides a standard Mac directory selection dialogue box IIRC. Alternatively, start R as per usual and then change into the correct directory using the setwd() function. You should probably update your R - 2.5.0 is 18 months old now, 2.8.0 is current. G
Searching the FAQ online I find: 12.1 How can I have a per session .Rprofile? You can by writing a .Rprofile file in your favorite session directory... So I think my specific question is how do I write a .Rprofile? I know it should be obvious, but is there a command to be called in the R console during a given session, or do I write a stub file outside of R (in a session directory?), open this using Preferences and then modify it in an R session? If the latter, how do I go about writing a stub and making R recognize it as a working directory, and what is a session directory/how can I find where the default session directory is located? Again, my apologies for being naive, and thanks very much for any help-- Andy Rominger
