Bonjour, Je developpe une application java et je veux integrer du code R dans mon programme .

I am unable to source a ".R" file using RJava. I tried a couple of different tests: 1) using java and the evaluation method core dumps 2) using ./RJava --example --gui-none to invoke source core dumps. 3) The line of R works if I go directly thru R and not RJava. Version info and code are below. Any help would be appreciated. --Laura O'Brien Applications

Hello, My colleague and I would like to write Java code that invokes R to do a simple TTest. I've included my sample java code below. I tried various alternatives and am unable to pass a vector to the TTest method. In my investigation, I tried to call other R methods that take vectors and also ran into various degrees of failure. Any insight you can provide or other Web references you

Hello all, I'm trying to run SJava package (0.65 modified downloaded from : http://stats.math.uni-augsburg.de/iPlots/alpha/) on windows NT 2000 and R 1.8.01.

Hi, Did anyone sucessfully install SJava package to R and was able to call R function from java in redhat linux8.0? I tried several days it still give me error either in libR.so or libjvm.so. for example, I can compile JavaRCall.java(a example with the SJava package) without problem. When I run it, it can connect to R and accomplish part of results, but fail for other calls. The outputs are:

Hello I m tryng to execute the code below and I have a problem with the R-Java connection.: import org.omegahat.R.Java.*; public class REvalSample { public static void main(String [] args) { String [] rargs = {"--slave", "--vanilla"}; System.out.println("Sample program to call R engine from Java"); ROmegahatInterpreter interp = new

Hello, Seems like it is almost working properly. I was able to run examples calling R from Java successfully for the java code below. However, some commands, such as "objects" when not commented out, give me the following error? If you could point me to the correct place to find a solution, I would much appreciate it. I am new to the R community and not sure where is the appropriate

org.omegahat.R.Java.REvaluator e = new org.omegahat.R.Java.REvaluator(); Object val = e.eval("objects()"); if(val != null) { String[] objects = (String[])val; for(int i = 0 ; i < objects.length; i++) System.err.println("("+i+") " + objects[i]); } hello, thanks to Philippe Grosjean's work I finally got SJava working (on Windows XP!!), so that I can

Hi, Here's some suggestions for troubleshooting the install. The CLASSPATH needs to be $SJAVA_HOME/org/omegahat/Jars/Environment.jar, $SJAVA_HOME/org/omegahat/Jars/antlr.jar $SJAVA_HOME/org/omegahat/Jars/jas.jar $SJAVA_HOME. This allows the java compiler/interpreter to find 1)the ROmegahatInterpreter and REvaluator classes(in a org/omegahat/R/Java tree under SJava 2)& the

Thank you very much. Weiming Zhang > .javaConfig

I am not a techie and have been struggling 2 days solid to try and install SJava (the source from http://www.omegahat.org/RSJava/).
