similar to: R matrices in memory

My computer is a pentium 4 running at 2.4 GHz. My R is 1.7.1 I have written a program in R that calls C++. The program spends most of the time in C++ ( > 90% ). R basically deals with output and input. How slower can this be compared with the program I would get from rewriting everything in C++? Thank you.

I tried to dynamically load a c++ function. Everything seems to be OK when dyn.load() is executed but then I get this error Error in .C("integral", sumInMean, sumInVar, boundError, numberSampleClasses, : C/Fortran function name not in load table The code of the function is something like this: #include <cmath> extern "C" { #include

Dear R users: I have a problem when installing the R package *gsl*. The procedure is as follows: (1) Since it needs a GSL vesion >=1.12, and the GSL library on the serve I use is too old, I download GSL 1.15 and install it in my own account, such as $HOME/local/gsl. Because I do not have root access, so it cannot be installed in standard folder. (2) Then I download the source code of R

Hi, I'm trying to install the gsl wrapper source code (http://cran.r-project.org/src/contrib/gsl_1.9-8.tar.gz) on a Linux system (OpenSuse 11.1), but encountering the following problem. I've already installed 'gsl' version 1.14 (ftp://ftp.gnu.org/gnu/gsl/gsl-1.14.tar.gz) on the system. What's missing? Thanks a lot... > R CMD INSTALL gsl * installing to library

When I try to install gsl in R I get the error Need GSL version >= 1.12 . However, I have version 2.3 of gsl installed on the system, which is picked up earlier in the configure process (see below).

Hi all, I am new to R and am writing after having contacted Robin Hankin, who maintains the R gsl wrapper. I am trying to use an AFNI (neuroimaging analysis) program that depends on the R gsl package. When I try to use the script I wrote, I get an error that led me to suspect the gsl package was a culprit. When I do library("gsl") within R, I get: Error in dyn.load(file, DLLpath

hello I maintain the gsl R package, and many users have recently reported that the package does not install from source under macosx 10.9 ("mavericks"). Users typically install the gnu GSL library and are able to compile and run a small "hello world" program which executes some of the Bessel functionality of the library; but under mavericks the configure script (which uses

As a workaround I created a symbolic link to /usr/bin/gcc-4.2, ie: sudo ln -s /usr/bin/gcc-4.1 /usr/bin/gcc-4.2 The correct behavior of the gsl package should be to use the executable

I did a complete update.packages() which reinstalled a great number of packages (I have a great number in my personal library). There were complaints about 4 packages, one of which was "copula", but "gsl" was not one of them. I would have *thought* that if "gsl"
