Hello all, I would like to request that getConnection() and the struct Rconn declarations be added to the R embedded interface. Here's why.

However, things get a little hairy once

I'm just learning how to use R right now, so I'm not sure what the most efficient way to organize these data is. I had subjects perform the same task twice with slight changes between the rounds. I want to analyze differences between the rounds. All of the subjects also answered a questionnaire. Putting all of one subject's information on one row seems sloppy. I was thinking about

When writing Ruby you have the option to end the file early with __END__. Anything after the __END__ is assigned to a constant called DATA which is available within the file. I recently tried using this in Rails and it didn''t work. Instead I get an uninitialized constant exception. Anyone know why? Has it been disabled in Rails? thanks Gavin

Hello, When I call an action with some invalid XML or JSON data a parse exception gets raised from within Rails/Ruby (REXML or ActiveSupport::JSON).

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, 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 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, 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

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.

I then tried a local R install as non-root with source packages: after
