Problem with launching JAGUAR in R

Windows XP, R 2.11.1, Java JRE6

I just installed the Jaguar package.

From an R console, I can do this:

> library(JGR)
Loading required package: rJava
Loading required package: JavaGD
Loading required package: iplots

Please use the corresponding JGR launcher to start JGR.
Run JGR() for details. You can also use JGR(update=TRUE) to update JGR.

and so JGR appears to be correctly installed.

JGR() yields

On Windows JGR must be started using the JGR.exe launcher.
Please visit http://www.rosuda.org/JGR/ to download it.

I'm not sure how to run Jaguar - I know I have to run jgr.exe - but should R be already open? If so, should the JGR library be already loaded? I've tried all of these, and what seems to happen regardless is a console window opens briefly, then disappears. I've run jrg --debug, with no apparent error message: (same file regardless of choice made above).

What should I be doing?

Thanks!

System: Version 5.1 (build 2600), platform 2 [Service Pack 3]

Have you tried the instructions from the JGR website?

 

Installation instructions:

1. Download and install R 2.5.0 or higher (Linux/Solaris: make sure --enable-R-shlib was used when compiling R)
2. Download the appropriate JGR application for your OS from above (Windows/Mac OS X) or install JGR package from CRAN.
3. Start the JGR application! JGR will install all necessary packages directly from CRAN (or the RoSuDa server). (You should have administrator rights to get the packages installed)
4. After step 3 completed successfully, JGR is fully installed and can be used.

Windows users: if you have more than one JDK version installed, you can use this tiny tool to select the default version that will be used with JGR: jselect.exe.

The Windows launcher accepts the following optional command line parameters:

--debug - show debugging info and create c:/jgrdebug.txt (must be the first parameter if used)

--rforge - use www.rforge.net for package installation instead of CRAN (useful to install latest development packages)

--cran=xxx - use xxx as CRAN mirror for package installation

--libs=xxx - use xxx as package location (use only if you don't have write permission in the default R package location)
