Help needed for Loading "tm" package
Thank Prof. Brian Ripley for your comments. Based on Prof Brian Ripley's comments, I checked Java environments in my PC. But I have not solved a "tm" package problem in Win R software. I am not sure but my current conclusion is that the Win-based R binary software has definitely a problem with Rweka package or subpackage. Should I wait for another upgraded R binary version under the window XP, "tm' package or Rweka ets? Or I'd better migrate to non-window OS such as Linux, etc?

Howdy Gurus again Thanks to Tony.Breyal, I was able to writing the following script for analyzing a text document. But I got an error with "tm' package. I don't why I got the error from the R script below. I think I followed proccess of R tm manual.
Please do read the messages you got. I see
Error in .jinit(system.file("jar", c("weka.jar", "RWeka.jar"), package =
pkgname, :
Cannot create Java virtual machine (-1)
so the problem is with your Java installation and RWeka, not 'tm'. First make sure you have a working installation of RWeka -- I suspect you do not even have Java installed, but it could be a version or path issue (but very unlikely to be an R issue).
I use R v2.8.1. and tm_0.3-3.zip under Win XP. Thanks in advance, Kum Hwang
