Here is the way that I do it instead of creating a package of my 
functions. I 'source' the file into an environment and then attach the 
environment to keep the global from being clustered:

# read my functions into a environment
.my.env <- new.env()
sys.source('c:/perf/bin/perfmon.r', envir=.my.env) attach(.my.env)

Is there a way to do this directly in .Rprofile without sourcing from a 
separate file?  I've looked at
sys.source, but don't understand how it works.
