similar to: fortran into R

Hi all, Thanks to everybody who thought on this problem, there was slight mistake in the fortran code which lead to NULL pointer allocation error, but still it surprises me that why it does not crib in the first run. The compiler I am using is absoft fortran compiler. Cheers, -Jag Jagadish Rangrej ( Statistician ) CHEO Research Institute, Ottawa, ON 613-7383951 > -----Original Message-----

I get an error when trying to compile a FORTRAN source file for use in a package that I am developing. The error, reported in 00install.out is below. * installing *source* package 'USGSstats' ... ** libs *** arch - i386 C:/PROGRA~1/R/R-214~1.1/etc/i386/Makeconf:194: warning: overriding recipe for target `.m.o' C:/PROGRA~1/R/R-214~1.1/etc/i386/Makeconf:187: warning: ignoring old

Dear all, I'm writing a code that requires Bessel functions with complex argument. Searching the list, I found the continuation of a thread I initiated a few months ago: http://tolstoy.newcastle.edu.au/R/e4/devel/08/03/0746.html As I understand, the most promising option would be to use the fortran or C implementation of Amos,

Hello, I have been trying to use a collection of Fortran subroutines to return a 2D array of calculated values to my R code, calling a Fortran wrapper subroutine from R. I've done this successfully before with C & C++ code. The Fortran wrapper subroutine which is to be called by R takes a set of input arguments & then should return an array of 2 columns & the specified number of

Dear R users, I'm porting a piece of Matlab code to R, but I'm now stuck with the following: I need an equivalent of besselJ(x, nu) that can handle a complex argument x. I couldn't find any R implementation. I did find a possible fortran solution in SLATEC (< http://www.netlib.org/slatec/ > , CBESJ-C), however I've never tried to use external C or Fortran code

I successfully used .Fortran to load and execute my fortran procedures under WinXP and 32 bit R. Alas, the same isn't true with my next Windows 7/64 machine, R 2.14.1 (64 bit) and the gnu gfortran (64) compiler (mingw64 v. 4.6.1). Though I'm able to compile the routines from the command line using gfortran '...', .Fortran('foo2') results in an error saying the Fortran

Hello everybody Is there a way to output data into a file like the unformatted, direct fortran files? That's the kind that can be opened with: open(30, file='file', format='unformatted', access='direct', rec=1000, convert='big endian') Thank you in advance Kostas Douvis

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

Here are three reasons for converting Fortran code, especially older Fortran code, to C: 1. The C-Fortran interface is not standardized. Various Fortran compilers pass logical and character arguments in various ways. Various Fortran compilers mangle function and common block names in variousl ways. You can avoid that problem by restricting R to using a certain Fortran compiler, but that can

Hi, "we can, once we know how to do it, 'drive' R from within FORTRAN" I am not sure I understand what you mean by this ... You can call routines written in Fortran or C from within R - how easy this is depends on the interfaces to those routines. You can call (some) R functionality from C (see for example

[cc'ing to R-devel] It's moderately obscure to me too, but ... There are two sets of bessel code in the package, one in C++ from Chris Bond and the other in FORTRAN from Netlib (I think). The FORTRAN code is the one that's giving trouble, you might try just removing the FORTRAN code from the src directory and trying again.

I browsed through ch.5 of R manual "Writing R extensions". It seems to be written for experienced programmers rathern than for people who occasionally face this problem. A table summarising the main ley points for each supported platform would be very useful. Something like: Supported languages: C, Fortran-77, ...... Windows guidelines: 1. compie Fotran code with (commands) from

Install the gmp package, run your code, and then try this: bu <- gmp::as.bigq(u) bs4 <- bu[1] + bu[2] + bu[3] + bu[4] + bu[5] s4 <- as.double(bs4) s1 - s4 ## [1] 0 s2[[2]] - s4 ## [1] 7.105427e-15 s3 - s4 ## [1] 7.105427e-15 identical(s1, s4) ## [1] TRUE `bs4` is the exact sum of the binary rationals in your `u` vector; `s4` is the closest double precision to this exact sum.

There is a new mailing list : FreeBSD-Fortran. The list is for discussion of Fortran related ports on FreeBSD: compilers, libraries, scientific and engineering applications from laptops to HPC clusters. Topics for discussion might include: - better integration of fortran ports, i.e. compilers libraries and end user applications - maintenance of unmaintained fortran related ports - user

Hello, I am trying to run a piece of Fortran code from R, and I am having trouble passing an array to the fortran subroutine. My attempts to pass an array into the fortran are producing memory errors, and I cannot find an example that performs the task. I have looked at "Writing R Extensions", and understand in concept what needs to happen, but all the examples are written in C.

I recently submitted a package to CRAN which encompasses Fortran 90 code. Neither on my linux system nor on the win-builder system the compilation reported any error or warning. The function worked fine. However, after submission of the package to CRAN, I received an email that I should not include Fortran 90 code. The problem is that the part written in Fortran is a large function using

Has anyone ever successfully used Fortran character strings with R? ?Foreign says R C Fortran integer int * integer .... character char ** [compiler dependent] Character strings are passed as C arrays of character strings to Fortran: the first string may be usable if its length is passed

Hi! When I run "R CMD check" on the current development version of my R package "frontier" [1], there is no difference between the output of the test scripts in the /tests/ folder and the saved output files (.Rout.save). However, if I change an R file in the /R/ folder, some calls to the Fortran code (called by ".Fortran()") return different results, although the
