[R] filename of source file

[David Richmond]

Yes, source refers to the use of the source() function. Suppose I invoke 
a file like so:

source("/path/name/filename.r")

I want to insert a command in filename.r like so:

fullpath <- magic_command()

such that fullpath is now "/path/name/filename.r"

In other words, I want filename.r to be able to figure out where it is, 
regardless of where I put it, so that it can save all its output in the 
same directory.
