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?
