Hi, I am looking for C/C++ codes for computing generalized inverse of a matrix. Can anyone help me in this regard? Thanks, Mahbub.

Dear All, I have been trying to compile a package for windows that we have written. Since R version 3.0.0 the package doesn't compile any more. (On Linux the package compiles without errors). The error specifically says: gcc -m32 -I"C:/PROGRA~1/R/R-30~1.0/include" -DNDEBUG -I"d:/RCompile/CRANpkg/extralibs64/local/include" -O3 -Wall -std=gnu99 -mtune=core2 -c

Hello, I'm using the eclat function of the arules package (1.0-6) for the identification of frequent itemsets. I need the tidLists, but if I set in the function tidLists=TRUE R crashes (Windows XP Professional SP3, 32 bit, R version 2.12.1 (2010-12-16), reproducible on two different computers) with two different error messages or non at all. Minimum examples are: library(arules)

Dear All, Under Debian GNU/Linux La.svd (with method = "dgesdd") sometimes gives the error "Error in La.svd(data, nu = 0, nv = min(nrow, ncol), method = "dgesdd") : LAPACK routine DGESDD gave error code -12" It seems not to depend on the data per se, but on the relationship between numbers of rows and columns. For example, if the number of columns is 100,

Hello, This simple SVD calculation (commands are copied immediately below) crashes on my Ubuntu machine (R 2.13.0). However it worked fine with R.12 and Ubuntu 10.04, and it also works fine on my Windows 7 machine with R 2.13, so I suspect there's a problem with (my?) Ubuntu and / or R. I'm using the R distribution that is accessible with Ubuntu's repositories manager, I am not

Professor Ripley commented on LAPACK error codes: https://stat.ethz.ch/pipermail/r-help/2007-March/127702.html and says "Internal LAPACK errors are usually problems with arithmetic accuracy, and as such are compiler- and CPU-specific." Is there a listing for the error codes from Lapack routine 'dsyevr'? Especially I am interested about the meaning and handling of error codes 1

Using the 64-bit Solaris compilers make check dumps core in La_rs at 73 F77_CALL(dsyev)(jobv, uplo, &n, rx, &n, rvalues, work, &lwork, &info); I can't reproduce it easily, but example(eigen) occasionally stops with Error: abs(sm - V %*% diag(lam) %*% t(V)) < 60 * Meps is not TRUE which might be connected. The tiny rounding errors in example(eigen) aren't

I have ported some R code to C to make it faster. I can perform .Call("foobar",....) once and it works fine. Absolutely correct answer. If I put a loop inside foobar and run the main code routine more than 100 times, it crashes R. Or if I call .Call("foobar"....) seperately more than two tims it crashes R. For the most part I am doing matirx multiplies using EXP

Hi, Over the past six months we have had a few problems with deprecation and Seth Falcon and I want to propose a few additions to the mechanism that will help deal with cases other than the deprecation of functions. In the last release one of the arguments to La.svd was deprecated, but the warning message was very unclear and suggested that in fact La.svd was deprecated. Adding a

Hello List, I have create a small package with C code. In the C code, I call Fortran routines of Lapack. Here is the call in the C function: F77_CALL(dgesvd)(&jobu, &jobvt,&size, &size,A, &size, D,U,&size,V,&size,&work1, &lwork,&error); In the src directory, I have a Makevars File with: PKG_LIBS = $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS) And in the

Fedora 9 R 2.7.1 I tried to install R on my Linux system using install.packages("Rcmdr", dependencies=TRUE). I received many, many, many error messages. I hope someone can suggest a fix. The output from warnings() is listed below. A more detailed list of errors from one of the failed installations is listed below the warnings: > warnings() Warning messages: 1: In

Lately I'm getting this error quite a bit: Error in La.svd(x, nu, nv) : error code 1 from Lapack routine 'dgesdd' I'm running R 2.5.0 on a 64 bit Intel machine running Fedora (8 I think). Maybe the 64 bit platform is more fragile about declaring convergence. I'm seeing way more of these errors than I ever have before. From R-Help I see that this issue comes up from time to

Hi, I'm just wondering if it is planned to include the Lapack routine DGESDD (and friends) in R-1.4.0? This is faster (supposedly by a factor of ~6 for large matrices) than DGESVD which is currently (R-1.3.1) called by La.svd. And if it is not in the plans yet, is there a chance it could be? I've added it to my local version of R-1.3.1 and so far see a factor of 4 improvement over

Dear all, I need to calculate tr(xyxy) fast for matrices x and y. Inspired by the R-source code, I've created the following functions (I am *new* to writing external C-functions, so feel free to laugh at my code - or, perhaps, suggest changes): #include <Rinternals.h> #include <R_ext/Applic.h> /* for dgemm */ static void matprod(double *x, int nrx, int ncx, double *y, int

Not an expert in programming either, but to me it seems like you've forgotten to initialize the variable "tr". It just picks up garbage from allocated memory previously initialized by other processes.

Any body here has used ruby-uml from http://ruby-uml.rubyforge.org/ ?? I dont know how to use it, would you mind to share your experience on it? OR Have you found plug-in or gem for generating application code like controllers, models, views to sequence diagram ? I have tried RailRoad, but it can not create sequence diagram, only class diagram for controllers and models. Thank You for your
