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).
