Hi, I am trying to run the example "JavaRCall" with SJava 0.65 and R1.5.1 under Windows NT4.0. Although loadLibrary("RInterpreter") worked successfull, the following error occurs: "Exception breakpoint occurred at line 65 of ROmegahatInterpreter.java. java.lang.UnsatisfiedLinkError: boolean org.omegahat.R.Java.ROmegahatInterpreter.initR(java.lang.String[]) boolean

I need to calculate a large number of t statistics, and would like to do so via matrix operations. So far I have figured out a way to calculate the mean of each row of the matrix: d <- matrix(runif(100000,1,10), 1000, 10) # some test data s <- rep(1,ncol(d)) # a sum vector to use for matrix multiplication means <- (d%*%s)/ncol(d) This is at least 1 order of magnitude faster than

Hi, I installed SJava 0.66-1 on my linux RH 7.2 machine. I am using R-1.7.1. I set LD_LIBRARY_PATH up then called library(SJava) and it was fine. But when I called .JavaInit(), I got weird error that states it could not find java/lang/Hashtable. The session is below and shows my java configuration. I am using j2sdk1.4.2_01 from Sun. Thank you very much. Weiming Zhang > .javaConfig

Dear duncan, I'm writing to ask you for some help about compiling SJava. I encounter some errors when I compiled SJava on Window XP: Building JNI header files...

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

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):

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

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
