How can I access a function created in one data directory in another? I have been sourcing the text file that contains the function each time I go to another data dir. This is cumbersome, and I suspect there is a way to make functions global. Thanks in advance, S.

There are several ways to achieve this. The ultimate solution would be to
pack your functions into a package and have it loaded at startup. See the
"Writing R Extensions" manual for more information on this. For other ways
see help(.First).
I'm using the following in my .First function:
attach("/home/pflugs/R/my.functions.R")
"my.functions.R" is a normal text file, created by dump(). It can also
contain data sets that I use frequently.
This works from wherever I am and I can keep my personal functions in
one place (making editing them easy). What's more, the functions don't
"pollute" my workspace (which tends to get overfull anyway), because they get
attached at their own position in the search() list.
I have to define .First each time I start a new working directory, but that's
a minor inconvenience.
