Dear all,

I am running Windows XP with several parallel installations of R (2.0.1; 
2.1 and so on). How can I install JGR for the 2.0.1 version? I keep on 
getting error messages when trying to install it.

Best wishes

Hi Christoph,

Which version of R comes first in your PATH?

I am sure Simon Urbanek et al. are happy to help you, but even the 
winners of the John Chambers Statistical Software Award are unable to 
help if you don't say what the error messages are and which versions of 
JGR you tried...

Markus is the winner, I'm just changing oil and doing dirty  
things ;). I'd be glad to help and, yes, http://www.rosuda.org/ 
lists.shtml is the right place to discuss JGR-related things in more  
detail.

In general JGR (and also JRI, rJava and JavaGD) uses the registry  
setting to determine the location and version of R. This setting is  
updated by the R installer if you leave the (D)COM setting checked  
(which is the default). This implies, however, that the sequence in  
which you install the various R versions matters - you should install  
the latest version last. If you want to edit the setting manually,  
use regedit and look into HKEY_LOCAL_MACHINE/SOFTWARE/R-core/R - it  
contains both the version and the path (at your own risk).

The most recent JGR for Windows can be installed simply with
install.packages("JGR",,"http://www.rosuda.org/R")
and then starting JGR.exe which can be found in $R_HOME/library/JGR.  
The package installation fetches the correct version for your R (2.0  
and 2.1 are supported only). The convenience installer is still  
provided at http://www.rosuda.org/JGR/1.2/JGR-12.exe
Mac binary and Linux sources of the new release should become  
available this week.

Cheers,
Simon
