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 _____________________________ Baptiste Augui? Phy...

Hi folks, I am planning to write some more time-consuming matrix manipulations in c++. What is the experience with the existing c++ matrix libraries? Do you have some recommendations? Are some libraries more compatible with R than the others? All suggestions welcome! Best, Ott
