I would like to call C routines from Fortran under linux as suggested in section 5.6 of the "Writing R extensions" documentation. I'm familiar with Fortran but not with C. I understand the example provided in Fortran: subroutine testit() double precision normrnd, x call rndstart() x = normrnd() call dblepr("X was", 5, x, 1) call rndend() end but I don't understand

...to see the source code of this function to check if my call is correct. I've not been able to find it in the R source distribution. Could anyone point the place of that file?

Having not much success with my previous question I try to reformulate it: I'm simulating a Markow chain in Fortran interfaced with R. Each loop of my Fortran calls various functions of the R RNG through the wrapper given below. In a run of 100 iterations of the Markov kernel, after 20 iterations, the RNG seems like frozen. For example, the first call to the RNG in my loop is:

Hi, I'm using R 7.0 under Linux as a programming interface to Fortran (g77 v0.5.24). Basically, what I want to do is to call a fortran subroutine of mine which performs MCMC computations. Apparently I'm getting into memory management problems. To track the problem I wrote the following small Fortran subroutine (saved as test.f) : subroutine test(n,p) implicit none
