Well, not in IDL completely, I think, there is also C and Fortran code underneath.

By the way, even the interface to an external code is implemented in R much more conveniently, compared to IDL. It took me several hours to make IDL to call my C functions from DLL. I have read the documentation carefully 2 or 3 times...

And I have done the same task in R in several minutes.
