In section 5.7 of the `Writing R Extensions' manual, it mentions the interface to numerical linear algebra routines (LINPACK, etc.). You will need to figure out which are the ones you need and how to call them. As these are expressed as Fortran routines, you can call them from C using the F77_CALL() macro mentioned in that manual.
I believe many would say that routines in Numerical Recipes are not really `industrial strength'... HTH, Andy > From: Kosuke Imai > > Hi, > I'm writing an R package using the C code i've written.
