Hello, all, I have the same question as the last mail I sent. I have installed libRmath in my system. But I still can not link Rmath through -lRmath. The whole process is as follow.Is there anybody who is so kind to help me find out the problem? I will appreciate very much. [credsim at confsys ~]$ cd /usr/lib [credsim at confsys lib]$ ls -l libR* -rw------- 1 bcdesai bcdesai 237828 Apr

Hello, I forgot to tell you that I am using Linux OS. And I can?t find directory "src/nmath/standalone". I will send you the test code I am using and the whole operation process. [credsim at confsys ~/src]$ gcc test1.c -o test1 -lRmath test1.c: In function `main': test1.c:18: warning: assignment makes pointer from integer without a cast test1.c:19: warning: assignment makes

hello, everybody, I create a package by myself named "var" on Linux system. I attach a C code which uses "R_ext/Lapack.h" in directory "src". But when I carry out " R CMD check var", it shows > wxt0124() Error in .C("wxt1221", PACKAGE = "var") : C function name not in DLL for package var Execution halted Could you tell me what is

hello, I create a package which includes C code and Lapack. But when I run " R CMD check ". an error message, "/usr/bin/ld: cannot find -lfrtbegin " occurs. could you tell me what is the problem? the detailed message is as follows: [credsim@confsys ~/src]$ R CMD check var * checking for working latex ... OK * using log directory '/home/credsim/src/var.Rcheck' *

Hi! I am studying C language to run with R 2.0.0. My system (Windows ME /BR) is configured to run RCMD ( I have installed ActivePerl, Rtools and MinGW as indicated in http://www.murdoch-sutherland.com/Rtools/ an with correct path). I would like run the coded write below named conv.c (Example from "Write R Extension") : #include <R.h> #include <Rinternals.h>

Hi R-Users I wrote 1 week ago asking about a message that appears when I try run dyn.load. I'm trying to do an example in C code from "Writing R Extension" to learn how to do it. I have R 2.0.0, Rtools, Perl and MinGW as describe in http://www.murdoch-sutherland.com/Rtools/ with path sets. When I use C:\R\rw2000\bin>RCMD SHLIB -o C:/dev-cpp/teste.dll

Hi everyone! I'm trying to lear how to call external C code in R but even the R help web-page example is drive me crazy. I copy-paste the example at: http://stat.ethz.ch/R-manual/R-patched/doc/manual/R-exts.html#Interface%20functions%20.C%20and%20.Fortran here is the example: void convolve(double *a, int *na, double *b, int *nb, double *ab) { int i, j, nab = *na + *nb - 1; for(i = 0;

Dear all, I'm studing how to include .c code in my .r functions . In the R-exts.pdf manual I have found the following code. At one point the author write "called from R by"... How can I load a .c file on R? ( I am using a xp windows as so.) Thank you ale void convolve(double *a, int *na, double *b, int *nb, double *ab) { int i, j, nab = *na + *nb - 1; for(i = 0; i < nab; i++)

Hi, I am hoping some one can help me. I am learning to use C and would like to learn how to call c code in R. I have look at Writing R Extensions and I tried to copy the example on page 38 void convolve(double *a, int *na, double *b, int *nb, double *ab) { int i, j, nab = *na + *nb - 1; for(i = 0; i < nab; i++) ab[i] = 0.0; for(i = 0; i < *na; i++) for(j = 0; j <

I've been attemping to create a test dll that contains R objects (actually I simply copied the code from the "Writing R extensions") and got it to build the dll using rcmd shlib main.c (okay, it's simple, but effective). Here's the info so far: this is the contents of the main.c file (not there's no WinMain()). Do we put it in or does the script do it when we compile?

Hi, I compiled a C program file on Borland C++ 5.5 compiler to get one dll output (as instructed in the file readme.package). The C program file is just the example on page 31 of "writing R extensions": void convolve(double *a, int *na, double *b, int *nb, double *ab) { int i, j, nab = *na + *nb - 1; for(i = 0; i < nab; i++) ab[i] = 0.0; for(i = 0; i < *na; i++) for(j = 0; j

Hello I'm trying to run a fortran code which use LAPACK subroutines. I think I should use some points shown in the manual 5.5 Creating shared objects but it is too technical for me :-(... Could anyone help me for the procedure to do: -which part of the manual is relevant for this type of question? actually I'm speaking from writing R extensions, should I read R admin? -point 1.2

Hi, I am happy to announce that I finished the translation of almost all LGPL'ed R headerfiles to Delphi. As a test I did several demos which basically contain delphized versions of all the examples of chapter 5 in "Writing R Extensions". Please have a look in the attachments for details (DemosAndHeaders.txt), more information (Readme.txt) and an example of how it looks

I have a function for plotting soil texture that I am having a problem with. The function is: plot.psd <- function(sand, clay, ...) { conv.ter <- function(x, y) { x.con <- 100 - x - y*cos(1/3*pi) y.con <- y*sin(1/3*pi) data.frame(x=x.con, y=y.con) } plot(conv.ter(sand, clay), xlim = c(0,100), ylim = c(0,100*sin(1/3*pi)), axes = FALSE, xlab="",
