Hi, I have some trouble with the result of a fortran function calling the R binomial RNG: The C function rbinom is wrapped as in the file attached. My main fortran program starts as call rndstart() and ends as call rndend() I happen to call the binomial RNG within a loop as b = ggrbinom(1.d0,0.5d0) write(*,*) 'b=',b In certain cases, after a few iterations in the loop, b get

Hi!!! It would like to know if it exists a form to use the functions to generate variates in FORTRAN with the same easiness I use that them in C? Or not? If yes. They would have some example? I would like to use the functions rbeta, rlnorm and others! Sorry my english..rsrsrs Thanks!!!              Fábio Mathias Corrêa    University Federal of the Lavras - Brazil Veja quais são os

Hi all, Is there a way that I can import R functions into Fortran? Especially, I want to generate random numbers from some not-so-common distributions (e.g. inverted chi square) but did not find any routines written in Fortran that deal with distributions other than uniform and normal. Thanks. Anny [[alternative HTML version deleted]]

Hi All, I have k identical parallel pieces of code running, each using n.rand random numbers.? I would like to use the same RNG (for now), and set the seeds so that I can guarantee that there are no overlaps in the random numbers sampled by the k pieces of code.? Another side goal is to have reproducibility of my results.? In?the past I have used C with SPRNG for this task, but I'm hoping

I recently developed an R package to make available a very large legacy program written in Fortran. My package has been rejected by CRAN due to this Write statement with the message "As 'Writing R Extensions' warns you against including Fortran I/O, this will not be allowed." The issue is that this Write statement does not involve I/O it is inernally writing an integer to a

I have dealt with this on so many platforms in the past that I should know the answer by now. I looked in V&R S Programming, R manuals and FAQ and still can't find the answer. In the Hmisc library I used the R scripts to build the package, which creates Hmisc.so. I have library.dynam('Hmisc', ...) in the .First.lib. When doing library(Hmisc) I get Error in dyn.load ....
