author-topic model in R

Hello all #rstats friends! I am wondering if there is a package/function in R that can do author-topic modeling? I browsed vignetes of topicmodels and stm for a while, with no discovery of this type of model.


Thanks for the guiadance @technocrat! Though I a still bit confused after looking at the reference manual, can you point me to a specific function or is there an example using lda for such modelling?

lda was a poor choice on my part. Its demo does not work. See, instead this post
