[R] How to make own function load automatically on startup

[Gabor Csardi]

Jonas, if you want the function to load really automatically, 
without running source of anything, read 

?Startup

Basically you need to create an .Rprofile file (its location depends
on your operating system) containing the R code you want to run
at startup.
