What is it? ----------- 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

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

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

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

Hello folks, I'm embarking on a project to embed R into the Apache web server, and I'd like your help. Currently, I'm looking for a way for R code to call back into a shared library from which the R shared library was loaded. Essentially, apache starts and loads mod_R.so which runs an initialization routine which calls Rf_initEmbeddedR() and the following code: /* override to

hi everyone, i know r since last summer and i love it. i'm studying economics and use it for econometrical tasks at university. besides that in a private project a buddy of mine and me do some economic evaluation with data stored in a MYSQL-database. we export the values from our online MYSQL database to analyse them offline with r. the results then also hav to be stored in the mysql. so far

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

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

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.

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

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 thnking off, just does not serve the purose of

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

I'm currently working on embedding R into the Apache2 webserver (with some positive results...), but I'm struggling to identify the best way to expose the apache data and functions to R. A couple of thoughts: In light of the recent discussion on "S3/S4 classes performance comparson", I'm leaning toward implementing the interface with S3 style classes. I appreciate

I''ve seen several postings where FastCGI is being used with RoR projects, yet, most of the material I''ve read (Dave Thomas'' book, online articles, etc) recommend not using FastCGI anymore because it is a dormant project and hasn''t been updated since 2003 (I think???). So, I went out and got Simple CGI instead. It had to be compiled and installed from

Hi All, I have centos 7. Apache and php are installed. CGI runs fine - php does not seem to run.
