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

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

Dear R-devel, Is there a way to find the size in bytes of a save() command --before-- the file has been saved? If not, can anyone point me to some resources on XDR so I can find a way to calculate it?

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

Hi, A few comments from a fairly experienced R user who worked for several years on a R-based bioinformatics analysis framework. I don't want to misrepresent anyone's views, but... There are real disadvantages to the "objects-as-C-structs" and functions/methods which "mutate" based on argument type. i.e. S4. (1)Novices simply don't understand it.

Bonjour, Je developpe une application java et je veux integrer du code R dans mon programme . Le programme de test que j’ai fait est : 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

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

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

Frank, Both RZope and Rho solve this problem. RZope (http://www.analytics.washington.edu/statcomp/projects/rzope/)solves it by using *nix's fork command, which takes as much time as a memcopy. Rho(http://rho-project.org) solves it by maintaining a pool of idling R processes, which it maintains active & can pull to do a calculation immediately. Both of these are pretty

Hello all, (Thank for your reply) I have a web-application in Apache Tomcat, when i start R in this application, I used packe RSJava Code ROmegahatInterpreter interp; String [] rargs = {"--no-save"}; REvaluator e; interp = new ROmegahatInterpreter ( ROmegahatInterpreter.fixArgs(rargs),false ); e =new REvaluator (); Errors ================ R version 2.10.1 (2009-12-14)

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:

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

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.
