[R] need help in building an R package with Fortran source

[Meinhard Ploner]

Hello all!

Can someone give me instructions how to build on PC/Win an R package 
with some embedded Fortran functions (preferable source, not dll!). The 
package should then be compilable and work on PC/Win as well as on Unix 
derivatives.

Thanks a lot
