Hi, I just started using R a few weeks ago and have a problem with linking Fortran subroutines to R. For some reasons, I need to compile a Fortran program in R (or Splus) and the whole program consists a couple of subroutines, say, subA and subB. There is no difficulty in linking the subroutines individually, but two subroutines are nested, as shown below, SUBROUTINE subA(arg.) EXTER...

Hi, I have a package of my own which seems to work fine under linux. I want to make a compiled version for windows. (I work with windows 2000 and R 2.0) I have followed the steps described in the file readme.packages (in the top-level directory of the binary installation) and I had a trouble at this step (which aim is not documented): C:\Program Files\R\rw2000\src\gnuwin32>make libR.a

Dear R-helpers, apologies if this is somewhere in a manual, I have not been able to find anything relevant. I run Windows Vista. I have some Fortran code in a subroutine, and have no problem calling this from R with .Fortran, compiling the code either with 'R CMD SHLIB' or independently with gfortran. But is it possible to have more than one subroutine in my source file, one depending on the other? Or is this not supported, or is there a trick? Of course,...

I am making my first attempts at using some Fortran code with R, and so far it's going OK. To print from my Fortran programs, it seems I need subroutines dblepr, realpr and intpr. From the excellent "Writing R Extensions" document: "Three subroutines are provided to ease the output of information from FORTRAN code. subroutine dblepr(label, nchar, data, ndata) subroutine realpr(label, nchar, data, ndata) subroutine intpr (lab...

Hi all, According to the documentation ( http://www.voip-info.org/wiki/view/Asterisk+h+extension): Be aware: Macros require their own h extension as they do not make use of the calling context's h extension! Does this apply to subroutines too? I am unable to find the corresponding explanation. If not: what happens when a call is hanged-up during the execution of a subroutine? Is the h extension in the parent triggered? And also: what happens if, in a stack of subroutines, each calling subroutine has an h extension, like this: s...

Hi, Let's say I do: Set(data=xxx,yyy) Gosub(my-sub,s,1(${data})) My subroutine will only receive "xxx" for ARG1. How can I pass a literal with a comma to a single argument in a subroutine? (The point is: when calling the subroutine I do not know if the variable has a comma or not.) Thanks, Daniel -------------- next part -------------- An HTML attachment was scru...

Asterisk 11.1.0 I'm trying to use the "b" subroutine of the Dial application so that I can do some stuff with our internal applications that need to have access to the called channel information. I can see that the subroutine is being executed, but the arguments I pass don't see to make it to the subroutine. [callmenow] exten => s,1,NoO...

A helpful link-time optimization would be to place subroutines that are used close together in time also close together in the executable file. That also goes for data that is in the executable file, whether initialized (.data segment) or zero-initialized (.bss). If the unit of linkage of code is the function rather than the compilation module, and the uni...

Dear freinds, The pl script file which is available in the asterisk monitoring section of the voip-info.com expects username ,password and host parameters . Which one we should provied is the acconts we registered for asterisk or any thing else your help will be immensely appreciated . with regards rk _______________________________________________________ Too much spam in your inbox?

Hi, Until you get a more definitive answer, I will make an attempt to give some advice. When using an assumed sized array (i.e. REAL*8 array1(*)) you still need to allocate the memory prior to calling the Fortran subroutine, so you would still need to know its maximum length. Arrays created in a Fortran subroutine via the use of the ALLOCATE statements are not simple arrays (in the sense of C like pointers), but are more akin to a C structure, in that they also contain information concerning the size of the array, s...

Dear helpers, I am trying to create a library which uses some Fortran source files and Lapack and Blas subroutines. The Fortran source files from the original author contain subroutines isamax.f, sgefa.f and sgesl.f, which are part of BLAS subroutines on my Linux computer, but maybe different (old) versions. So in addition to these subroutines, there are other Lapack and Blas subroutines involved. There is n...

Hi, I am a FORTRAN developer and I am 'translating' R functions in FORTRAN subroutines. I am 'new' to R. It's my first question in this mailing-list and English is not my natural language. Very often, an R function gives an 'array' as result and you don't have to bother with the dimension of the array : R creates automatically an array with the good length...

I have no experience with incorporating Fortran code and am probably doing something pretty stupid. I want to use the following Fortran subroutine (not written by me) in the file SSFcoef.f subroutine SSFcoef(nmax,nu,A,nrowA,ncolA) implicit double precision(a-h,o-z) implicit integer (i-n) integer l,i,nmax double precision nu,A(0:nmax,0:nmax) A(0,0) = 1D0 do l=1,nmax do i=1,l-1...

Thanks for the useful information. We notice that the idea of LIPO also can help LLVM LTO if LLVM has FDO/PGO. And regarding Diablo, we'll learn from it and I think we'll get some good ideas from it. In MCLinker, the detail of the instructions and data in bitcode are still kept during linking, so some opportunities to optimize the instruction in bitcode become intuitive. Instruction

I used "R CMD SHLIB" to compile the fortran filename.f file and the filename.so is generated. But since in filename.f it calls another subroutine written in C, i had problem in "dyn.load" because it could not find the C subroutine. I have the .c file but don't know how to tell R about it. How should I compile when I want to call the fortran function in R which calls (FORTRAN-callable) C-code? Thanks a l...
