[R] Problem with Snowball & RWeka

[A N]

The Java error when attempting to use the stemmers in the Snowball or
tm packages on Windows machines is caused by Quicktime. See prior
posts in this thread.

The workaround is to uninstall Quicktime.

After much trial and error on machines spanning WinXP/2k/Vista/7, I
finally verified this as follows:
1) Fresh installation of Windows/Java/R. Snowball package works perfectly.
2) Install Quicktime. Java errors produced when attempting to use
Snowball package.
3) Uninstall Quicktime. Snowball package works perfectly again.

Many thanks to profs Ligges, Hornik, and Feinerer for their kind help
in diagnosing this.
