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.
You mean you want all your definitions in the Rprofile file? The way to
do that is to use local(). That is,
.my.env <- local({
f <- function(x) x^2
# all your other definitions
environment() # Put this as the last line, to return the environment
that local() created, where
# all your definitions now live
})
attach(.my.env)
