I am working on a text mining project using to classify test using Naive Bayes.

When I build a Naive Bayes classifier using 

classifier<-naiveBayes(training, type)

then run the predict function on test data:

pred <- predict(classifier, test)

I get: 

Error in object$tables[[v]][, nd] : subscript out of bounds

What would be the cause of this error?

The training and testing data was a Matrix of Characters. When I converted into Numeric, I never faced this problem again.
