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.

I have read the documentation carefully 2 or 3 times...

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