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

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

Byron, I just read your blog (statcomp.blogspot.com, linked from your other post) and rand across your idea of an R/Flash graphics device. I've also been giving this some thought because of this amazing interactive flash app: http://tools.google.com/gapminder and others from http://www.gapminder.org/. I would love more than anything to work on this. The only hitch is that I'm so

Hello all, I would like to request that getConnection() and the struct Rconn declarations be added to the R embedded interface. Here's why. It's common in CGI scripts for web applications to direct stdin, stdout, and stderr map to reading from the browser, writing to the browser, and writing to a web log file respectively; very nice and neat. However, things get a little hairy once

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

For those R user's who don't subscribe to R-sig-db and are having troubles with the latest RMySQL binary on CRAN, please read the email thread at the end of this message. RMySQL 0.7-2 does work with MySQL 5.1, however the CRAN binary is linked against the 5.0 version.

Hi, Is this sufficient? if (.Machine$sizeof.pointer==4){ cat('32\n') } else { cat('64\n') } Or is it better to test something in R.version, say os? I'd like to use this to specify appropriate linker arguments when building the RMySQL windows package. Jeff -- http://biostat.mc.vanderbilt.edu/JeffreyHorner

Basically, the way puppet installs things things with /usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install <package_name> fails due to authentication WARNING: The following packages cannot be authenticated But if I do it from an ssh console normally, using apt-get install <package_name> it works fine without issues. Is there a way to change how puppet uses the

In R-2-4-branch r39548, Rcons_vprintf is called from stdout_vfprintf when R_Outputfile is NULL. When called and output is greater than R_BUFSIZE, output is truncated to R_BUFSIZE.

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

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 all, I've been working on a new R Graphics device that targets Adobe's Shockwave Flash format (SWF for short). It uses http://www.libming.org/ on the backend. Here are some example outputs so far: http://160.129.129.41/~hornerj/plots/ Once you click on the above, choose a directory like 'smooth' and then click on test.html to see a side-by-side comparison of the swf

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

A professor here at Vanderbilt sent me the following code. Each of the text strings should right justify against the center vertical bar, but because of font issues it doesn't. I understand that there are workarounds, but I was just curious if this was consistent across all platforms. On linux with R 2.7.1 and R-trunk (r46103), both acrobat reader 8 and kpdf render it incorrectly. How

Hi all, I am facing facing performance issues with our web servers which is working for concurrent 250 requests properly and then stops responding when the requests are more than 250 . The current configuration parameters are as follows : apachectl -version Server version: Apache/2.0.52 Server built: Jan 30 2007 09:56:16 Kernel : 2.6.9-55.ELsmp #1 SMP Fri Apr 20 16:36:54 EDT 2007 x86_64

I made two decisions this afternoon that are now related to each other. 1. Use more of the modules that exist in the Forge 2. Rebuild my monitoring server As I perused the various modules that help with managing monitoring packages my eyes fell upon a module that reported to be able to manage nagiosql, a setup that I had been planning on migrating my nagios monitoring to. So I installed
