Since upgrading to 2.12.0, I'm having trouble getting the JGR to start under Windows 7, but I'm not quite sure what's happening. When I try to run the JGR.exe stub, the dialog says can't find Java R interface jri.dll. As nearly as I can tell from a Google search this is to be a part of the rJava package which seems to load fine with the library(rJava) command from the Windows R GUI. Indeed the required .dll is sitting in C:\R\R-2.12.0\library\rJava\jri as expected. I must admit that my understanding of Java stubs is limited, and I don't know why this stopped working with the upgrade. My ultimate goal of was to run the Deducer package which ironically runs fine from the Windows GUI despite recommending that I use JGR instead. Any hints how I recover the use of JGR?

JRI/rJava/JGR have their own mailing lists, and it would be better to ask there. But there was a rJava update this morning, and it is consequently little tested. (I know for example that 64-bit JRI will need furtehr work.) It may be that other things also need an update (like the JGR stub). So do ask those who know for sure -- they don't read this list.

hi rob, i encountered the same problem on a students laptop and have no idea anymore after trying updating, re-installing and just about everything. like you say, the jri.dll file is exactly at the same place as on your machine. let me know if and how you solved it! thanks, kat -- View this message in context: http://r.789695.n4.nabble.com/R-2-12-0-and-JGR-tp3002706p3003554.html Sent from the R help mailing list archive at Nabble.com.
hello mike, it would be helpful to know what you have done, what system you are working on etc. "JGR for Windows and Mac OS X consists of two parts: JGR R package which is available from CRAN and JGR launcher. The latter is a small program that starts JGR from its R package. It can be also used to install all necessary packages. Consider updating JGR from CRAN (e.g. via update.packages()) periodically to have the latest bugfixes etc." you should find all necessary files on http://www.rforge.net/JGR/index.html good luck, kat -- View this message in context: http://r.789695.n4.nabble.com/R-2-12-0-and-JGR-tp3002706p3298703.html Sent from the R help mailing list archive at Nabble.com.
