Use library(Rserve) Rserve() instead. You need to setup PATH correctly in order to run it manually - please read the documentation it is explained there: http://www.rforge.net/Rserve/doc.html > and also i can't realize backstage running of Rserve by technique of > Multi-thread in Java. Can anyone tell me why? Windows doesn't have fork(), so you cannot have more than one session in one Rserve in Windows. Use of a unix computer as a server is highly recommended as that allows arbitrarily many connections in parallel with almost zero startup overhead. On Windows you can still spawn multiple Rserve instances in parallel, but make sure you're not trying to connect to the same instance twice. > So, before i run the Java, i must run the R manually, then input > "Rserve()" or "system("Rserve")".

Again - just read the documentation - all you need is correctly installed R and R.dll on your PATH. > For example, i tried to input "Rserve()" to the .Rprofile of R, but > when i run the R, hundreds of processes were started, then my computer > system was down. would anyone help me to solve this problem? Cheers, Simon PS: Please use stats-rosuda-devel mailing list for questions on Rserve, JGR, rJava etc. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
