Hi Antoine, I have got this to work on Windows, the process should be the same for Linux.
For an eclipse plugin you will need to add the following to your MANIFEST.MF file: Bundle-ClassPath: <whatever you normally have>, lib/JRI.jar Bundle-NativeCode: /lib/jri.dll; osname=winxp; processor=x86 You will also need to ensure that the R executable is in your path and that R_HOME is set. I did this by creating a simple batch file containing the following in a directory called rootfiles within our feature, the same should work for a .sh : set PATH=%CD%\<R install>\exe;%PATH% set R_HOME=%CD%\<R install> eclipse.exe I then added the following line to the build.properties file of the feature: root=rootfiles This tells eclipse to copy the content of the directory to the root of the application on install. If you then run eclipse from the batch file, it should work. -- Geoff Gibbs mangosolutions data analysis that delivers Tel +44 (0)1249 767 700 Mob +44 (0)7791 855 620 -----Original Message----- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of GRAN Sent: 25 June 2009 09:40 To: r-help@r-project.org Subject: [R] JRI - problem to access "stats" package Hello, I am a new R user. More precisely, I am working with JRI (on a Eclipse Java6 project under Ubuntu9). I have difficulties to access some R packages (For example: package "stats", object "Normal", function "pnorm"). I have tried many solutions to set the right path but nothing have succeed: For example: LD_LIBRARY_PATH=${R_HOME}/lib:${R_HOME}/bin:${R_HOME}/library Inside the java code, I have also tried such methods: Note that "r" is the REngine object coming from the connection to R r.eval("dyn.load(\"/home/gran/workspace/R-2.9.0/library/stats/libs/stats .so\", local = TRUE, now = TRUE)"); r.eval("require(stats)"); r.eval("autoload(\"Normal\", \"stats\")"); r.eval("search()"); r.eval("ls(\"Autoloads\")"); System.out.println(r.eval(".Autoloaded")); r.eval("zval = .95"); System.out.println(r.eval("print(zval)")); r.eval("p3 = pnorm(3*zval)"); System.out.println(r.eval("print(p3)")); It gives as a result: [STRING "stats"] [REAL* (0.95)] null <---------- p3 = null because pnorm is unknown Do you know how to use the "stats" package with JRI ?
