[R] 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?
