I don't think there is such a thing.  source() looks in the current
working directory, it doesn't use environment variables to do a wider
search.

Of course, you can always make up your own variable, and then do
something like

source(paste(getenv('MYDIR'),'/x1.R',sep=''))

and that will work from anywhere if MYDIR is defined properly.
