[Rd] R with Java
Hey, I´m a newbie in R and have a big problem. I hope, I´m in the right mailinglist, if not, sorry for this. I want to use R in my Java application and I found out, it should work with JRI. But it doesn´t. I installed it and in the lib-directory of R there is a folder named "JRI". But I have to tell Eclipse that the JRI exist but I don´t know how. I read help-files and so on, but I don´t understand. Could you give me a simple instruction how to do this? Very very thank you.

Not really since I don't use Eclipse, but in general you just have to make sure that the necessary JAR files are on your class path, then you have to make sure Eclipse sets the java library path to the path with the jri.dll and finally PATH must contain the directory of R.dll. (Also since this is a new project, you may consider using the high- level REngine API instead of the low-level JRI API. In addition, unless you have a specific reason for using JRI (R embedding) there are more simple solutions such as Rserve based on the same API - but the choice depends on what exactly your applications is doing) Cheers, Simon __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
Re: [Rd] 2.10.0 Under development (unstable) (2009-09-15 r49711) just built segfaults on Debian Squeeze
Just downloaded and installed "R version 2.10.0 Under development (unstable) (2009-09-21 r49771)" and am happy to report that my .Rprofile loads appropriately with no segfaults. Thanks Duncan!

[Rd] DYLIB_EXT vs. SHLIB_EXT?
The graph Bioconductor package wants to compile its C code to a shared library that is named differently from the package, to avoid conflict with graph.dll and friends from graphviz. So recently we tried after: $(SHLIB) mv $(SHLIB) BioC_graph$(DYLIB_EXT) and useDynLib(BioC_graph) in the NAMESPACE. This fails on Mac. We then shifted to after: $(SHLIB) mv $(SHLIB) BioC_graph$(SHLIB_EXT) which works on all platforms we have available. Have we found a robust solution?

[Rd] cannot build R-devel (>= r49747)
