JGR, JAva and Macintosh

Then the first error in the original message occurs:

The error message after a double click on JGR.app is a popup-windows  
with following message:

Cannot find JRI library

Cannot find java/R interface (JRI) library (libjri.jnilib)
Please make sure you start JGR  by double-clicking the JGR
application

If you upgraded R or used a custom package path before, you'll have to  
remove your JGR preferences
rm ~/.JGRprefsrc
and re-try. If that doesn't help, please run JGR from the command line  
(Terminal) as follows and post the output:
/Applications/JGR.app/Contents/MacOS/JGR

Thanks,
Simon

Some additional notes:

It looks like a Java problem. The preinstalled version on the Mac
was 1.5.0_16, but I switched to 1.6.0_07. Below are error messages  
for
library(JGR) and library(iplots)

You cannot load JGR from within an R session due to Os X 10.5
limitation - you should use the launcher supplied on the JGR website.

Cheers,
Simon

Proceed at your own risk as iplots cannot resolve potential ev.loop
