[R] Bessel functions of complex argument

[baptiste Auguié]

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
