Help needed for Loading "tm" package

Kum-Hoe Hwang
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.

I use R v2.8.1. and tm_0.3-3.zip under Win XP.

Thanks in advance,

Kum Hwang

Please do read the messages you got.  I see

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).

Re: Help needed for Loading "tm" package

Kum-Hoe Hwang
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?

Re: Help needed for Loading "tm" package

Prof Brian Ripley
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.

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

Re: Help needed for Loading "tm" package

Kum-Hoe Hwang
I appreciate alll helpers for R.

I have struggled with Rweka problem related with "tm" text mining package in R.

My problem was solved when I replaced RWeka_0.3-15.zip with
RWeka_0.3-13.zip under the OS of Win XP.
Now my tm package works fine in R. I don't know why it works.

Thanks all who gave me good help
