Hi My code is as following: #include <R.h> #include <Rinternals.h> //* the Projector part *// void Projector(double *L, int *dimL, double *G, int *dimG, double *W, int *dimW, int *xymod, int *dimxy, double *modif, int *dimif, double *Lsum) { ...} //* the interface part *// #define getDim(A) INTEGER(coerceVector(getAttrib(A,R_DimSymbol), INTSXP)) SEXP Projector5(SEXP L, SEXP G,

It's tough to reliably reproduce, but I often get stack imbalance warnings when calling max.col() on non-real/double matrix. The code is conditionally PROTECTing but not incrementing its nprot counter for the eventual UNPROTECT. Pretty sure this would fix (but I haven't tested it): Index: array.c =================================================================== --- array.c (revision

Joyful. I'm adapting a FORTRAN 77 package for use with R. Pretty straightforward. Except for a glitch it took me some time to figure out. This existing package has subroutines which have parameters called "NA". So, I called subroutines like bnodes <- function(n, lst, lptr, lend, nodes, nb, na, nt) { ensure.all.numeric(list(n, lst, lptr, lend, nodes, nb, n.a, nt),

I have the following contrived code in package format. On Solaris and Mac OS X, code runs just fine. On Windows, it crashes the R environment with the "Send Bug Report" dialog. I tried R 1.8.1 (Win2K) and R 1.9 (WinXP) binaries with the same result. PCs otherwise appear properly configured for creating R packages. Anything blatantly wrong? Suggestions? TIA Relevant files from package

This is a question and maybe an announcement. We've been discussing in the group that it would be nice to have a mechanism for something like "inline" C/C++ function calls in R. I do not want to reinvent the wheel, therefore, if something like that already exists, please give me a hint -- I could not find anything. If not, here is a working solution, please criticise so I could

Hello, is there any one who uses C++ STL classes when programming shared libs for R and has had any problems with STL? In the very simple example below I am constantly getting segfaults when trying to populate the queue. The segfault occurs at what looks like a random index in the loop when pushing another element to the queue. Reproduced on 4 machines. Object x is an Image as in EBImage,

Hi All, I have a Rails application that needs to be served from a Fedora Core 3 Linux server. The application runs well as a "plain" CGI application. My next step was to speed things up with FastCGI installed via "gem install fcgi". (version 0.8.6.1). That approach lead to this error in the fastcgi.crash.log: Dispatcher failed to catch: undefined method

Hi, Below I have a mickey-mouse example using Oleg Sklyar's wonderful inline package. The question I have is, how do I return multiple values, say in a list? Inside the C code, I've also calculated 'sum'. How do I return this along with 'res'? Ultimately, I want to return multiple matrix results. Thanks in advance for any code snipplets/advice! Regards, Ken #

I've been studying some of the code and I'm still a little shakey on the proper method for returning a data.frame from a C function (which is my ultimate goal here). I've started some code that I've "stolen" from the archives and I'm running into crashes, etc. I've been trying to gleen some insight from the src/main/scan.c file and didn't find many comments in

Dear all, I am testing a simple C++ function that takes a double matrix as argument and which uses routines provided by the C++ Armadillo package. I am aware of the nice capabilities of Rcpp and RcppArmadillo which helps simplifying a lot and that I have already successfully tested. However, I had a hard time trying to figure out how the coercion from a REALSPX matrix to an arma::mat =

I am using C code to create an S4 object based on Douglas Bates's example in his lecture notes on <http://www.ci.tuwien.ac.at/Conferences/DSC-2003/Tutorials/RExtensions/slide s.pdf> http://www.ci.tuwien.ac.at/Conferences/DSC-2003/Tutorials/RExtensions/slides .pdf e.g. SEXP La_DGE_dc(SEXP A) { SEXP aa = PROTECT(duplicate(A)); SEXP adims, pivot, val; int

Hi, all! My project today is to write a speedy colSums(), which is a function available in S-Plus to add the columns of a matrix. Here are 4 ways to do it, with the time it took (elapsed, best of 3 trials) in both R and S-Plus: m <- matrix(1, 400, 40000) x1 <- apply(m, 2, sum) ## R=16.55 S=52.39 x2 <- as.vector(rep(1,nrow(m)) %*% m) ## R= 2.39 S= 8.52 x3 <-

Hi, I have followed the recommended steps for creating a package (rctest). As of now, my goal is simply to understand how various pieces fit together. The package includes: (1) C code with source in sub-directories, compiled to create a static library. (a) There is a single C-struct (dns) a simple 'matrix': {int m; int n; double *d;} (b) C code to create random matrix of a certain size.

Hi, I ran R (version 2.9.0) CMD build under root in Fedora (9). When it tried to remove "junk files" it removed EVERYTHING in my local account! (See below). Can anyone tell me what happened, and even more importantly if I can I restore what was lost. Panickingly, Jarrod [jarrod at localhost AManal]$ R CMD build MCMCglmm_2.05 * checking for file
