Dear all,

I'm writing a code that requires Bessel functions with complex argument. Searching the list, I found the continuation of a thread I initiated a few months ago:

http://tolstoy.newcastle.edu.au/R/e4/devel/08/03/0746.html

As I understand, the most promising option would be to use the fortran or C implementation of Amos,

Sadly, my limited programming skills don't include any knowledge of fortran, and I have never managed to link external code to R functions (i'm missing a simple example based tutorial, R-ext overwhelms me with information).

A few questions for anyone interested:

Many thanks,

baptiste
