Dtm and topic models in a supervised setting

[nicolasdugue]

Hi,

The tmtoolkit package is great and I really enjoyed working on my corpus with it. However, I am now working in a supervised setting, I have a train corpus and a test corpus. Thus, I want to build my dtm model on my train corpus and then use the same vocabulary to get the dtm of my test corpus. Similarly, I would like to train my topic model on the train corpus, and then, use the topics uncovered to get the document-topic matrix of the test corpus.
Is there a way to do so on tmtoolkit ? Or is it planned in the future ? I did not find any way and thus used ad-hoc code.

Regards
