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/he...

...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 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 s...

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 call apache library write routine */ ptr_R_WriteConsole = Rapache_WriteConsole; /* load source(). I assume this is appropriate. I could always move this to the code that han...

...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 implementation is too complex. I'd like to simplify...

...perl-5.12.4-164.fc15.i686 What I did was the following: · Downloaded the package, rapache-1.1.15.tar.gz · Ran configure --with-apache2-apxs=/usr/sbin/apxs, make, make install. · Added this to my httpd.conf: o LoadModule R_module /usr/lib/httpd/modules/mod_R.so o o # Output R errors and warnings to the browser o ROutputErrors o o # Displays information about rapache and R o <Location /RApacheInfo> o SetHandler r-info o </Location> Also added the Directory directives but commented them when I wa...

...to "production" yet? For storing pointers in R variables, I've been using integer vectors which is what RMySQL does but doesn't seem natural.
