[Rd] Call R function from Java

Hey guys,

It worked. All I had to do is set PATH = < R directory > in my system
variables in "My Computer" and that was it!

Oh btw Simon, I couldn't find the run.bat in the JRI_0.2-4.tar.gz file. I
found a "run.in" but that is a unix bash script.

Another question:

When I'm evaluating R expressions:

I sometimes get back form the println:
	RXP[unknown/19, id=1208787616, o=null]

Is there anyway to actually view that output as a string? I know it's not a
graphical object. It's probably a type of error message.

I'm running Windows XP, 1GB RAM, 2 x 1.8GHZ Xeon P4's, Eclipse 3.1.1,
jdk1.5.0_07, and jre1.5.0_06

I don't know either, but I'd recommend using the run.bat start script  
supplied with JRI. I bet Brian's guess is correct.

There are examples in JRI (in the "examples" directory) and JGR is  
probably the best example of the general use of JRI. At your  
suggestion I have now added a FAQ.
