Thanks, it works quite well in my MacOS.

Yet, in a linux machine (Fedora 9, R version 2.7.2, latest rJava and 
RWeka versions has found in the berkeley server), sometimes the save 
function produces a Segmentation fault. Since I am working with large 
datasets (email filtering), I wonder if there is any 
bug/limitation/problem of rJava/RWeka for large models (e.g. NaiveBayes 
with more than 1000 inputs).
