similar to: Using Fortran 95 in an R package?

Is it possible to run Fortran 95 code from R? I don't think so, but hopefully someone can prove me wrong. Here is the test I tried: A little fortran 95 subroutine: subroutine allloc() real, dimension(:, :), allocatable :: a integer :: n n = 10 allocate(a(n,n+1)) end I then compiled: >g95 -c allloc.f >R CMD SHLIB allloc.o Here is what happens when I try to dyn.load it in R 2.1.0

Dear list members, In re-running with GLMM() from the lme4 package a generalized-linear mixed model that I had previously fit with glmmPQL() from MASS, I'm getting a warning of a convergence failure, even when I set the method argument of GLMM() to "PQL": > bang.mod.1 <- glmmPQL(contraception ~ as.factor(children) + cage + urban, + random=~as.factor(children) + cage +

I have been revising some FORTRAN 77 routines in R packages I have previously submitted. Since R is now using gfortan I experimented with some Fortran 90 code (array intrinsics primarily). So far the code is still in F77 fixed format, in files suffixed .f (not .f90), but incorporates some F90 constructs. It has worked fine in linux/R. I tried to follow the thread of previous discussions

I am writing a function in fortran 95, but the intrinsic function MATMUL is not working properly. Here's an example. SUBROUTINE mymult(x,y,res,m,n) IMPLICIT NONE INTEGER :: m,n REAL :: x, y, res DIMENSION :: x(m,n), y(n,m), res(m,m) res = MATMUL(x,y) END SUBROUTINE mymult R CMD SHLIB mat.f95 In R: dyn.load("mat.so") x <-

Hi all, I'm looking into using LLVM to do some optimisations of Fortran code. As part of this, I've been trying to build the frontend with f95 support. At the moment, I'm trying to resolve undefined symbol problems for code defined in c-common.c + elsewhere - I'm taking the temporary approach of copy-pasting it into a new file, and linking that in. I have no idea if it will

We have a user here who is attempting to compile a package which requires f90 (gfortran will do). Our version of R was built with f77 (g77). When the user attempts to build the package, f77 is always invoked and fails due to the presence of f90 features. Is there a simple method or some documentation on how to force a package build to use a different compiler than the one used in

To all. I need your help. The big question is: How do I make an R library with Fortran 95 files? You may assume that I am a pretty decent programmer in both R and Fortran. I lay out a scenario and need your help! I know how to make an ordinary R package and have dabbled with R + Fortran 95 *.dll linking. I do not have a great handle on the whole Makevars file and whatever else I might need

Hello! I am creating a packege and I would like to inclued some Fortrun subrutines. I have two questions. 1. Can I use "free form fortan" - compiles well usinf g77 -ffree-form. 2. Is it enough to place the ".for" files in scr folder? Thank you in advance for any help! Ales Ziberna P.S.: I am runing R 2.1.1 on Win XP, SP2. I installed rtools, mingw, perl as suggested in the

I am reading the manual sections illustrating how to call a Fortran subroutine from R. I feel uneasy at the explicit statement about ".Fortran" interface working with Fortran 77. I would like to call a Fortran-90 subroutine from my R script. Is that supported at all ? Thank you, Maura tutti i telefonini TIM! [[alternative HTML version deleted]]

Anyone know what to do about this: make[4]: Leaving directory `/proj/llvm/llvm-test-1/External/SPEC/CFP2000/173.applu' make[4]: Entering directory `/proj/llvm/llvm-test-1/External/SPEC/CFP2000/178.galgel' /usr/bin/f95 -w -S -O2 /opt/spec/CPU2000v1.3.1/benchspec//CFP2000/178.galgel/src/modules.f90 -o modules.c -fixed -kind=byte -dcfuns -dusty f95: unrecognized option '-kind=byte'

Hi, I found some bottlenecks in my R code with Rprof. First I wanted to rewrite them in C, but a colleague keeps suggesting that I learn Fortran, so maybe this is the time to do it... I like to learn new languages and do it fairly quickly. I would appreciate the advice of others about these questions: 1) I hear bad things about Fortran. Sure, F77 looks archaic, but F90/95 seems nicer. Is it

Hi all, (Originally posted to r-help) I'm porting a package that I've worked on for OS X to Windows. The package is written in F95 so I need to compile it with gfortran and link it with gcc4. I've been trying to build an R with gcc4 without luck so far. If there is a binary of such a thing info would be appreciated. This package requires a Makefile. My question is, how can I find

Hi! Is there any package on CRAN that uses Fortran-90/95? I would like to study it. Thanks, Gregor

Chris and Bill, I have tested the proposed patch from... http://lists.cs.uiuc.edu/pipermail/llvmdev/2008-August/016490.html under i686-apple-darwin9 and it solves the problems building gfortran from llvm svn. The resulting compiler works fine so can we get that patch in before 2.4 is release? Jack ps We do have one oddity left in llvm-gfortran from current llvm svn. I find
