Calling R functions from Java
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.

Rserve and R to R communication
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

some questions about startup Rserve
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

Rserve needs (but cannot find) libR.a (or maybe it's .so)

Chrooted R + Rserve
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

Rserve alternative?
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

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.

Rserve compilation error
Hi, I am trying to install Rserve 1.7-0 on CentOS 6.

RServe
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

'system' command through Rserve
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

Rserve (Anyone?)
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 =
