[R] Path to R script

[Johannes W. Dietrich]

There is certainly a trivial solution for my question, but I can't 
find the answer in the documentation.

I need a platform independent method to obtain the file path of the 
current R script.

My working group uses R on several machines with different operating 
systems including Mac OS X, Windows and Linux, and for obvious 
reasons the file hierarchies are very different. Therefore, it would 
be useful to be able to address data files and external procedures 
relative to the path of the script.

Thank you for any suggestion,

J. W. D.
