Hi, I'd like to know whether there is a package (or more, of course) regarded as a good example that could be used also as an instructional tool for newcomers to R extensions development.

php-5.3.3-3.el6_2.6.x86_64 2.6.32-220.4.2.el6.x86_64 After some testing we moved our production PHP intranet site from an old server to a new CentOS 6.2 instance running the mentioned versions. At first it worked well and then user's started to experience a hung site. Upon some digging it appears that the PHP module is getting stuck in a race condition regarding the sessions file - [root at

I am fitting 3 parameter model to my response matrix and want to generate item characterstic curve. I want to specify file name to save item characterstic curve by passing it as external parameter to the R batch script. The following is the code I have written for this. *R Script:* library(ltm) cmd_args = commandArgs(); for (arg in cmd_args) cat(" ", arg, "\n",

Dear my friends... Anybody would be so nice for telling me the solution of my problem. My Apache2 can not start.

Hello, I am trying to setup a node.js based website called 'hummingbird'. It's a monitoring package that you can read about here: http://projects.nuttnet.net/hummingbird/ My question is when I hit the site all I see is a directory listing http://107.21.183.42/hummingbird/ Similar to what would happen if you went to a php site without php being configured in apache with the

Hi. CentOS 5.4 64-bit with SELinux, happily running for over a year, suddenly httpd fails to start up, getting an error message like: Starting httpd: Syntax error on line X of /etc/httpd/conf.d/php.conf: Cannot load /etc/httpd/modules/libphp5.so into server: libxml2.so.2: failed to map segment from shared object: Permission denied I turned off SELinux and was able to start httpd.

Hi. I've found inconstancy between output of repoquery and rpm. I was looking forward towards apache php 5.4 module which must provided by some package SCL (can someone tell me?). rpm -qf /etc/httpd/modules/mod_proxy.so httpd-2.2.15-29.el6.centos.x86_64 repoquery -qf /etc/httpd/modules/mod_proxy.so so repoquery results in no output yum list installed httpd Loaded plugins: fastestmirror

Dear all, in my package 'stochvol' I have unsuccessfully been trying to make a C routine called 'sampler' available to be called from other packages' C code. Following http://cran.r-project.org/doc/manuals/R-exts.html#Linking-to-native-routines-in-other-packages I have included #include <R_ext/Rdynload.h> R_init_stochvol(DllInfo *dll) {

Hi, I want to make use of some C routines from other packages to write extensions in C. In "Writing R Extensions", it says there is an experimental interface to support this in (or from ?) R 2.4.0. I had a dummy library containing src/dummy.cpp and R/zzz.R: ====== src/dummy.cpp ==== #include <R.h> #include <Rinternals.h> #include <R_ext/Rdynload.h>

To new R-Programmers: This long-winded note gives an example of optimizing in R that should only be of interest to newcomers to the language. Others should ignore. My hope is that it might help illuminate some basic notions of code improvement, looping, and vectorization in R. However, I welcome comments from anyone that enlarge, correct, or improve it. I remain a novice R programmer. For the

Hi, I'm using dyn.load to load a shared library (compiled from C code) into R. If I dyn.unload it and then dyn.load it again, I get an hourglass icon in Rgui (R 1.7.0, Win 2000), and it just sits there forever. I can't press Escape to stop the current computation, but I can close Rgui without resorting to using the Task Manager. Is it a problem with my use of R_alloc? Do I need

Martyn, No, that didn't work. One other thing in the mix (which I don't think is the issue) is that I call one of the C-entry points of expm. So the DESCRIPTION file imports expm, the NAMESPACE file imports expm, and the init.c file is #include "R.h" #include "R_ext/Rdynload.h" /* Interface to expm package. */ typedef enum {Ward_2, Ward_1, Ward_buggy_octave}

Hello, I need a bit of handholding with R, specifically, with writing packages for it. I'm a systems programmer, and am, on the request of several users of our software, working on generating R interfaces. For starters, I've written the following R function (which compiles): SEXP myincr(SEXP Rinput) { // Returns input integer incremented by one int input; SEXP returner; PROTECT(Rinput =

I have read both the historical r-devel threads and the most recent one regarding this. After reviewing the code, it would seem to beg for a linked-list implementation vs. an array implementation. This has several interesting consequences. Cons: 1) We pay for dynamic allocation every time we register a DLL. This isn't a problem in the grand scheme of things as registering a DLL results in

Hi, I'm trying to access the current R global environment from within C, using R_GlobalEnv. In the example below, Rgui (R 1.7.0. Win2K) crashes when I try to run assignValueToFooInR_GlobalEnv, but not when I run assignValueToFooInRhoEnv with Rho=.GlobalEnv. Can anyone tell me why?
