[R] Good Programming Practice Question - Functions in Different Files

[Paul Hiemstra]

Hi,

I always use source for this kinds of things. If you have a lot of code, 
you could consider wrapping it into an R-package. This would allow you 
to load all the code by using the library(myPackage) command. But this 
might be unnecessary for your situation.

cheers,
Paul
