LDA 1.1 is now on CRAN

Your favorite package for running topic models in R has been updated! This one not only has bugfixes and more utility functions, it also has two new models:

  • The Networks Uncovered by Bayesian Inference (NUBBI) model which discovers connections between entities in free text (run demo(nubbi), note that because of licensing reasons, I could not include the data for this demo in the package);

  • the Relational Topic Model (RTM) for discovering patterns which account for both document content and connections between documents (run demo(rtm)).

And because it’s on CRAN, everyone (including windows users) can install by simply executing install.packages("lda"). Please install, play with it, and let me know if you find any bugs.
