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 org.omegahat.R.Java.ROmegahatInterpreter.initR(java.lang.String[]) native code" All paths (attached) are set up correctly, what is missing?

Environment: R - 1.9.0 SJava - 0.67 Windows 2000 I can get SJava to work just fine in R but I am having trouble getting R to work in Java.

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 base omegahat interpreter libraries from which the ROmegahatInterpreter & REvaluator classes descend.(Found in those jar files) on Unix-like systems, the LD_LIBRARY_PATH has to point to the shared objects(so)/d...
