Using R from Java
Hello, I am interesting in using R from a web application, for basic statistics and plots. The server is Java-based (tomcat). The simplest solution is a system call that generates the text or the image, then the servlet forwards the output. This can be done from any language, but it is quite inelegant and slow for the initialization time. Is there any package or approach for accessing R from a

error: C stack usage is too close to the limit.
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.

Embedding R and registering routines
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

When collected warnings exceeds 50
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

R as a server on Linux
Hi, I am trying to avid the somewhat costly startup overhead of launching a separate R executable for each "client" request on Linux. My current architecture is such that My Java client explicitly calls R in batch mode and passes it certain parameters. The initital startup takes almost 10 seconds because R has to load a bunch of libraries as well as a moderately large, previously

rapache memory problem
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?

problem loading rgdal with Rapache, problem solved due to libexpat with apache.
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

mysterious rounding digits output
Well pointed out, Jim! It is infortunate that the documentation for options(digits=...) does not mention that these are *significant digits* and not *decimal places* (which is what Joshua seems to want): "?digits?: controls the number of digits to print when printing numeric values." On the face of it, printing the value "0,517" of 'ccc' looks like printing 4
