R help - Sep 2015 - Maxent package - Restriction on number of unique class labels

Hi everyone,

I am developing a text classification code in R using 'maxent' package.
I
see that there is a limit on number of unique class labels that can be
modeled, which is 255. Can someone please help me understand why this limit
is present?
The data I am working on has about 400 labels (data consists of thousands
of records). Can anybody please suggest which package to use to be able to
achieve maximum entropy based text classification on this?
I have tried using 'RTextTools' package as well. It seems to be
internally
using 'maxent' package in return and  gives me the same error.

Would really appreciate any help!

Thanks.

I have never even heard of the package but it might be just that that is the
default maximum number of labels programmed in.

Have a look at the manual and/or the actual function.  If you don't get an
answer in a day or so, email the author or maintainer.
