How do you account for the fact that the package passed its checks on
the build machine, e.g.
http://cran.r-project.org/bin/windows/contrib/2.8/check/RWeka-check.log
and no one else is reporting this? (And it does work for me.)
Blaming your tools is easy, but doing so on a public forum is
disrespectful and against the rw-FAQ
http://cran.r-project.org/bin/windows/base/rw-FAQ.html#Can-I-install-packages-into-libraries-in-this-version_003f
(note the word 'unsupported').
Uwe Ligges does a great job helping Windows' users by building binary
packages, and deserves your thanks, not vague and unsubstantiated
blame.

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?
You definitely shou;d read and follow the FAQ, as this could well be a
Java incompatibility with the binary package.

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
