...-------- mod_R is a project dedicated to embedding the R interpreter inside the Apache 2.0 (and beyond) web server for the purpose of writing web applications in R. It's composed of three parts: mod_R: the Apache 2.0 module that implements the glue to load the R interpreter. RApache: the R package that provides the API for programming web applications in R. libapreq 2.0.4: an Apache sponsored project for parsing request input. If you don't want to compile and install this version, then you can specify which libapreq2 library to use during configuration. T...

Hi all, I need your opinion about using R-Rapache to build a knowlegde base to bioinformatics field. I have copious amount of genotype information (some few million records) and would like to store it in MySQL database. Then, using RMySQL connector I would like to use it for further analysis using R over a web interface. The web interface which...

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...

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 HTML version deleted]]

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 refre...

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 com...

...9;ve found that comes close to a solution to this is creating an RObjectTable and attaching that to the search path. Assignments to variables in that environment can call the table's get routine which is defined in the application, and I think that might be an interesting solution for a new RApache implementation. For the RApache Project, the mod_R.c shared library get's loaded into the apache process and its purpose is to initializes R. Next, it calls 'library(RApache)' to load RApache.so, a package that implements the RApache API. This two-library system works, but the impl...

...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 know after collecting some information, i think the best approach to reach that goal is: * using mod_R / RApache to run multiple instances of r on the server, * build a website that will serve as frontend/gui for r either with html/php or some ajax-framework, * connect R to the database with one of the available db-packages to fetch the survey-data * put the r-scripts for analysis somewhere on the server * u...

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...

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 downloading the latest tarball and unzipping: ./configure --prefix=/opt --enable-R-shlib make make[3]: Ent...
