Hi, I do not have Linux myself but looking at your error message > > .JavaInit() > [1] error initializing manager class can't find class > java/lang/Hashtable Error in .JavaInit() : Couldn't start > Java Virtual Machine: can't find class java/lang/Hashtable > >
it looks like you have not set the JAVA_HOME variable correctly. On a Windows XP machine you will get the error (together with a popup dialog): > library(SJava) using JAVA_HOME = /c/Program Files/Java/j2sdk1.4.0_02 Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library "c:/PROGRA~1/R/rw1071/library/SJava/libs/S Java.dll": LoadLibrary failure: The specified module could not be found. Error in library(SJava) : .First.lib failed > See help(.Renviron) how to set the JAVA_HOME environment variable. ***Note*** on Windows XP (and maybe on other systems too) you have to set JAVA_HOME differently if you have i) Java Runtime Edition or the ii) Java SDK. For Java SDK, which you have, you have to set JAVA_HOME=C:/Program Files/Java/j2sdk1.4.0_02/jre/ and not to JAVA_HOME=C:/Program Files/Java/j2sdk1.4.0_02/ as one would guess. But with Java Runtime Edition you should do JAVA_HOME=C:/Program Files/Java/j2re1.4.1_02/ If you use ~/.Renviron it won't mess with your other settings. Again, I'm not sure if this applies to Linux, but it's worth a try.
