Hi Rusers,

I am having a hard time understanding/finding a solution to this error
message of RWeka.
I just want to use Xmeans clustering command but when I typed "XMeans" then
I get the following message:

Error value[[3L]](cond) :

  Required Weka package 'XMeans' is not installed.

So I tried to install "XMeans" with WPM (I thought this was a solution like
install.packages()), but when I WPM() then I got this error message:

> WPM("list-packages", "installed")

 Error .jcall("java/lang/System", "V", "setOut", out) :

  java.lang.NoClassDefFoundError: Could not initialize class
org.bounce.net.DefaultAuthenticator

I am not a Java user and have no idea how to solve this issue to use Weka
via R.
That would be appreciated if anyone could help!

Best,

Takatsugu
