[R] Questions on user defined function

[R. Michael Weylandt]

1. It's your choice, but it's entirely possible to define multiple
functions in the same file or inline. If you want to read from a file
though, you have to do it with source().

2. Yes. This is the idea behind the package system.

In short, R is much nicer about functions than Matlab.
