As others have suggested, you will probably find that constructing a
package is the best choice. However, there is an alternative that has
not yet been discussed. You can save one or more functions and data
sets to a file (see ?save) then on starting another session attach
that file (see ?attach).
The process is like
foo <- function(x) mean(as.numeric(x), trim = 0.3)
save(foo, file = "myproject/rfunctions/saved.rda")
then, when starting a new session, use
attach("myproject/rfunctions/saved.rda")
The .rda extension on the filename is commonly used for saved R data
sets but you can also have function definitions in a saved file.
