Hello, it seems that rJava tries to detect the path to the Java Virtual Maschine from a registry key which is not installed. I gues that the HLM means HKEY_LOCAL_MASCHINE where you find normally the path to your installed Java. On my Windows System i have for example the path HKEY_LOCAL_MASCHINE\Software\JavaSoft\Java Runtime Environment\1.6.0_24 where you can find the key for the Java installation path. Try to open regedit fromyour Windows console and convince yourself that the path is not present.
Maybee a reinstallation of the JRE or JDK helps (for the registry key). Or try to put your Java installation (the location) on the OS system path (open the Windows Shell and type Java -version if a installation is already on the system path), maybee that helps, too. Also, does it matter where java is installed? Yes, it does matter because the OS has to find the executables and native libs of the JRE and rJava has to find them, too because it relies on them. I hope this helps. -- View this message in context: http://r.789695.n4.nabble.com/rJava-software-tp3383366p3383977.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
