Hi all; Now I'm developing web application by using rapache in ubuntu. My problem is that as users execute the application, the server PC cumulates memory. After users close or refresh the application page, the server PC memory is still cumulated. Now I'm renewing apache machine by manually in terminal. Is there any way to kill memory when users refresh or close the application page?

Has anyone had problems with Rapache that don't show up on command line execution of R? I just ran into this loading rgdal in Rapache page and having a problem with loading shared object. The final complaint was that Stop_XMLParser was undefined- this was surprising since grep -l showed it in expat lib and it worked fine from command line. Finally, I noted the search path had apache/lib ahead

Hi, this is Charlie and I am trying to embed R in my apache server. However, I am having problem with installation. The R projet says that we can install add-on package with command $R CMD (rapache.0.1.4.tar.gz). However, I try to use it in command windows (windows xp) and an error shows. Please tell me when I can use the command (in c?? or in the same folder with the file). thx. [[alternative

Hello all, I searched on the www but could not find installation instructution for rapache on windows. The page says that the release runs on UNIX/Linux and Mac OS X operating systems. Has anyone been able to configure it on windows? Any idea how to go about it? Thank you.

Hi all I was trying to isntall RApache last week but ran into strnge problems that no one else seems to be experiencing. At least I couldn't find anything after extensive googling. First off, the machine I'm installing on looks like this: Dell Optiplex 745 32 bit 2GB RAM Fedora 15 httpd -v Server version: Apache/2.2.21 (Unix) Server built: Sep 13 2011 13:46:23 R: R-2.14.0-3.fc15.i686

I am trying to set up a RApache server on my Ubuntu 8.04. I have installed apache2, R-2.7.0, and the RApache plugin. Both Apache and R seem to work fine, but whenever i try to use the plugin i get this error: C stack usage is too close to the limit. I have tried to recompile apache2, R, and RApache, but i keep getting the error. The weird thing is, i had exactly the same problem when i installed

Hello, First presented at DSC2005, rapache is a project supporting web application development using the R statistical language and environment and the Apache web server. The current release runs on UNIX/Linux and Mac OS X operating systems. http://biostat.mc.vanderbilt.edu/rapache/ rapache 1.1.0 now supports Apache threaded web servers, but the Apache Prefork Multi-Processing Module is

Hello, The use of .Call and the like all depend on loading shared libraries and registering routines from it. Also, .Primitive and .Internal depend on routines being registered in the R binary. And applications that embed R can override routines declared in Rinterfac.h, but is there a way for an application embedding R to register other routines defined in the application without loading a

Hi, I've been tracking down a memory leak in an rApache application, http://data.vanderbilt.edu/rapache/bbplot. The code was deployed in 2007 and has survived numerous upgrades of both R and rApache (including upgrades and bugs in RMySQL). It's written in such a way so that web crawlers will download every possible URL the app will create. It's not a high-traffic app, but just about

I'm trying to get Cairo and RApache to work together on OS X leopard. Initializing Cairo stops the whole HTTP response. Apache logs show this message: Break on __THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC__ () to debug. The process has forked and you cannot use this CoreFoundation functionality safely. You MUST exec(). This reference

Charles, Greg, the problem is that Apple's FreeType on Leopard uses CF calls (albeit just to get files), so it breaks on fork. (The message is moot, because the whole point of using fork is to *not* use exec). In any case the solution is to compile your own version of freetype, fontconfig and cairo without any CF or Carbon API. Fortunately most recent versions of FreeType will do so

dear r-community, currently i have a workflow as following: data in online-MYSQL-database via .csv into R for analysis, results back to mysql. generating graphics for reports also. that's ok, but i need some process-optimization. i'd like to run r directly on the webserver. analysis should work automatically, after the appropriate r-script was selected in a browser-gui for R. until

I installed mod_r according to the specifications, and have been trying to get the demo script to work correctly. I am running debian, the latest build of R, apache 2 with prefork mpm, and the latest mod_r. Is anyone else using this module successfully? I added: LoadModule R_module mod_R.so <Location /test/hello> SetHandler r-handler Rsource /var/www/html/test.R RreqHandler

Hi, I've been trying to get a shared library version of the R package(version 2.12.1) installed on a CentOS 5 system. (It installs fine without but other packages demand shared libs - namely Rapache). I've tried this with yum but don't know of any flags to set to tell it to installl with shared libs enabled. I then tried a local R install as non-root with source packages: after

Hi everyone, I'm building a website (http://yourpsyche.org) using Jeffrey Horner's awesome Rapache module. I want to take user input, and pass it to an R script. At first I was simply using if else statements, but after a while I had so many nested if else's in my code that my head was spinning. So then I started using cat() and source() to write temporary files and read them back in
