Hey guys, I got a java gui app which loads up data into a table. How can i use R to perform statistical functions on the data in the table? P.S My question is not particularly geared towards Java coding, but more towards allowing R functionality within Java.

Dear All, The "clients.txt" file of the latest Rserve package, by Simon Urbanek, says, regarding its R client, "(...) a simple R client, i.e. it allows you to connect to Rserve from R itself. It is very simple and limited, because Rserve was not primarily meant for R-to-R communication (there are better ways to do that), but it is useful for quick interactive connection to an

I realize the communication between R and Java with Rserve in my dissertation, but i can not run the Rserve by double click of Rserve.exe, and also i can't realize backstage running of Rserve by technique of Multi-thread in Java. Can anyone tell me why? So, before i run the Java, i must run the R manually, then input "Rserve()" or "system("Rserve")". This

I want to use the R functionalities in my Java program. I found the Rserve that appear to suite my requirements but I'm facing some configuration problems.

I have successfully installed Rserv (http://stats.math.uni-augsburg.de/Rserve) on Mac OS, but I have trouble on two different linux platforms.

I successfully chrooted R running Rserve with an unprivileged user, and thought I'd publish the process. Attached is a jailkit.ini for use with jailkit;* and a chroot/setuid wrapper, chwrap.c. To set up the chroot in, for instance, /var/R; perform: mkdir -v /var/R jk_init -v -c jailkit.ini -j /var/R R then create the unprivileged user `r': useradd r After compiling chwrap

The Rserve documentation at http://rosuda.org/Rserve/doc.shtml#start states that even when making multiple connections to the Rserve, Windows won't separate workspaces physically and share environments, which will obviously cause problems and should therefore not be used. Are there any alternatives for the windows platform? Ralf

Hello, I'm using Rserve with Java and although it works OK for 50 or 60 requests, eventually Rserve simply stops responding and I have to force-quit and restart Rserve. During this time the JVM is fine and Tomcat (app server) is fine, too. The basic Java code does this: -------------------------------------------- 1. Create an R Connection 2. Execute an R Script via Rserve "eval"

Hi, I am trying to install Rserve 1.7-0 on CentOS 6. But I get this compilation error - /usr/lib64/Revo-5.0/R-2.13.2/lib64/R/lib/libiomp5.so: undefined reference to `pthread_atfork' I tried other versions of Rserve (0.6-5 and 0.6-8) without any success. How do I get around this issue? My goal is to run FastRWeb (which uses Rserve). Thanks in advance. Joydeep. -- View this message in

Hi all, is there a way to properly terminate Rserve instead of killing the process? I run Rserve in a linux box that serves my Java client.. I have a cronjob that runs Rserve every morning. However, I'm killing it at night manually for the moment. Is there a way, given host/port, I can run an R command to properly terminate it?? Thanks a lot in advance!! - yoooooooo -- View this message in

Hi all, I'm trying to run Rserve on windows RGui. It installs successfully but when I use "Rserve()" to invoke the service it shows following error: "The program can't start because R.dll is missing from your computer. Try reinstalling the program to fix this problem." I even tried reinstalling R but it still shows the same error. Thanks, Anand [[alternative HTML

Hello, I've installed an Rserve instance on a remote server. I have no problem interfacing with it and running most commands. I have loaded some R scripts on the remote server, and one of them contains a system command to copy a file (created by the script) onto another server. When I run the script on the remote server itself, the script works as I intend: it creates a .csv file and uses

REXP has an asBytes() method. Will this capture the output of an R plot function if a proper graphics device is used? It appears R insists on sending plot output to a file. Kind of strange since it insists on loading all your data into memory before it can do anything. If so then does anyone know what this would be? I prefer png or jpeg. Example: c is an RConnection REXP r =
