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. I have also downloaded the PDF Calling R from Java and when I want to execute the following code: import org.omegahat.R.Java.*; import java.io.*; public class Essai{ public static void main (String [] args) { REvaluator e = new

List, In order to get rid of some old, unreadable S3 code in package sp, I'm trying to rewrite things using S4 methods. Somewhere I fail, and I cannot sort out why. In order to isolate the problem, I created two functions, doNothing<- and dosth, and both should do nothing. The issue is that in most cases they do nothing, but in some cases dosth(obj) changes the class of obj and breaks with

Hi I'm trying to use SJava and I have troubles. I try to run examples from "Calling R from Java" but,I have an error that "fatal error: enable to open the base package" I heard SJAVA bug, so,could you send me your compiled SJava package with the modified REmbed.c because in Windows i'm not able to recompile!!! --example package org.omegahat.R.Java; public

Hello all, We currently have a java web utility that allows multi-threaded data analysis using S+. We want to migrate it to R. However, the guy who preceded me here left some documentation indicating that he couldn't implement it because R didn't support threading. Also, he noted that the R-Java interface(org.omegahat.R.Java.REvaluator) wasn't thread safe even if R was. Can

Hi, I am trying to run the example "JavaRCall" with SJava 0.65 and R1.5.1 under Windows NT4.0.

Hello all! I recently install R-1.2.3 and Omegahat SJava pkg (formely Java pkg) 0.62 and tried running the examples by issuing "scripts/RJava --example --gui=none" and I got the following: Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library "/usr/lib/R/library/ctest/libs/ctest.so": ld.so.1:

Hi, I had a 2 node distributed cluster running on 3.1.1 and I added 2 more nodes. I then ran a rebalance on the cluster.

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/). Does anybody have a binary file for me (I am Windows XP and rw2001)? I have tried installing Perl, mingwin and the cygwin tools but still no luck. When I try “R CMD INSTALL c:\SJava_0.78-0.tar.gz” I get the following (and haven’t a clue what it could mean):

Thanks for Professor Ripley and Brad's reply. UnsatisfiedLinkError: SJava.dll is gone. But, I have another problem. I have been trying to figure out, but, without success.

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, 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

Aaron, I mailed in the same mail twice (by mistake), you answered both copies. Differently! In any case, I've re-read what exists. I'm dumping what I understand here, so that we can discuss in detail. I'm using MachO as the example object format, as the ELF code is totally broken and outdated. Lets use the following as the basis for our discussion? There are 3 classes which

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

Hi everyone, We seem to have allowed our documented target-independent intrinsics to acquire a somewhat-haphazard naming system, and I think we should standardize on one convention. All of the intrinsics have 'llvm.' as a prefix, and some also have some additional prefix 'llvm.dbg.', 'llvm.eh.', 'llvm.experimental.', etc., but after that we lose consistency. When
