Multinomial Naive Bayes Classifier

Question

I have been looking for a multinomial naive Bayes classifier on CRAN, and so far all I can come up with is the binomial implementation in package e1071. Does anyone know of a package that has a multinomial Bayes classifier?

Have you tried `NaiveBayes()` in the `klaR` package? I haven't used it, but I know it's an extension on the version in `e1071`. — John Colby, Jan 15 '12 at 23:00
Thanks for the suggestion, I'll see if it implements a multinomial classifier. — Timothy P. Jurka, Jan 15 '12 at 23:30

bnlearn not doing it for you? http://www.bnlearn.com/

Is on CRAN, and claims to implement "naive Bayes" network classifiers and "Discrete (multinomial) data sets are supported".

Thanks for this suggestion. I'll test it out and see if it works for multinomial data. Unfortunately `bnlearn` doesn't support compressed sparse matrices as input, but I can deal with that. – Timothy P. Jurka Jan 15 '12 at 23:30

When I look at the bnlearn docs, I do not see an option to use a multinomial likelihood estimate for features. It says the features are assumed to be Gaussian distributed. Am I reading something wrong here? – gabe May 21 '14 at 19:59
