I'm new but am already starting to accumulate utility functions for the fairly specialized kinds of data files with which I work. I'd like to keep those functions in a single folder, or filetree rooted at a specific folder under my $HOME (I'm running linux), for ease of * source()-ing * git commit to bitbucket * scp to clusters I'm wondering, 1 is there a canonical location for personal functions, notably on linuxen? 2 how can one make that location most easily available? or must one always provide either a relative path from one's R cwd, or an FQ path to, the personal-functions folder? Apologies if this is a FAQ, but I didn't see anything about it @ http://cran.r-project.org/doc/FAQ/R-FAQ.html http://cran.r-project.org/doc/manuals/R-admin.html or in casual rseek-ing. TIA, Tom Roche <Tom_Roche at pobox.com>
[newbie] storage/use of user's own functions?

Hi Tom, I don't believe there is a standard location. You can set variables or have functions run (say to source other functions in) in your .Rprofile file. That way, you always have them. Once you get more than a handful of functions, it is probably time to consider putting them into your own package. This allows you to document them etc. then accessing them is as easy as loading your package. Also makes checking and distributing to others easier of that ever comes up. Hope this helps, Josh

May I endorse Josh's suggestion to consider writing your own package to include them. I put off doing this for too long. There is a bit of learning to do first but the investment will repay itself. You need the extensions manual, at least the early chapters.
