Dear R users,

I'm porting a piece of Matlab code to R, but I'm now stuck with the following: I need an equivalent of besselJ(x, nu) that can handle a complex argument x. I couldn't find any R implementation. I did find a possible fortran solution in SLATEC (< http://www.netlib.org/slatec/
> , CBESJ-C), however I've never tried to use external C or Fortran
code together with my R code, so I'm not sure where to go for a simple solution.

Any advice welcome,

Best regards

baptiste
