[R] Re: how to define functions in such a situation

[Sean Davis]

Look at the documentation for "source".  You can source a file directly 
from the web:

source('http://myserver.com/somefile_on_web.R')

If that file contains R code for three functions, the functions will be 
"visible and useable immediately" in your workspace.
