 Dear all

Currently, I'm implementing the generalized hyperbolic distribution into
Splus. Unfortunately the Bessel function is not implemented in Splus. In
R the Bessel function does exist but it is an internal function and I'm
not able to look at the code.

Is there any possibility to see the code of the Bessel function in R or
does anybody has an implementation of the Bessel function in Splus?

Thanks a lot for your help.
