Where to get support for Rserve?
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"

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 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

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

[Fwd: Re: Video demo of using svSocket with data.table]
Forwarded to R-Help, because I think it could interest people following this thread. Clearly, RServe and svSocket have different goals and very little overlap.

Using Rserve
Hey is there a more consistent way of connecting to Rserve. I have code that opens a connection to Rserve by executing explicitly using Java runtime ( "C:\Program Files\R\r20XXX\Rserve.exe" ). However when i run the app and attempt to connect, it does not connect imediately.I have to close the app and open it again for a few times before i get a connection. Am i doing something wrong?

Rserve compilation error
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.

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

Non-blocking Eval
