I noticed this while playing around with my xkcd post. When I choose a very small value of lambda, the term rankings look odd:

I also see these error messages:

Consider the term "bruce". Here is the data that createJSON() sends to the browser:

     Term logprob loglift      Freq Total Category
631 bruce -6.5192   3.338 0.8203917     2  Topic22

Note the estimated term frequency (within topic 22) is less than one. However, in ldavis.js, we set the lower bound of the domain to be 1. It should really be 0.
