Implement tidiers for topic models from stm package about tidytext HOT 9 CLOSED

Hi,
is this currently in development? I'd love to combine tidytext and stm for teaching in mid October and a tidier function would be most useful for this.

from tidytext.

I worked on this some today and it is almost good to go! Should be ready very shortly, in time for your course.

that's awesome, thank you so much for this :)

@methodds Got this finished up this evening. Give it a go and please let us know if you run into any problems!

Hi,
I just tested the latest version and it works without any issues, again thank you so much for implementing this! :)

There's only one suggestion that I have for your example in stm_tidiers: STM offers the spectral method for model initialization which, unlike the usual initialization for LDA models, is deterministic (more details on that in the STM vignette). The spectral method is highly recommended by the STM authors.
For this reason I think you should remove the seed, set.seed(2016) and just slightly adjust the stm call to topic_model <- stm(inaug, K = 3, verbose = FALSE, init.type = 'Spectral').

Sorry just another quick question related to this: Do you have a time schedule for the next CRAN release? I dunno about other countries, but university courses in Germany start mid/end October and getting devtools to run in our labs is a real pain.

@methodds I will see what we can do about a quick-ish CRAN release! I'd like to get the tidyeval stuff all worked out for all the functions.

from tidytext.

@methodds Just a heads up that the version of tidytext with stm tidiers is on CRAN now.
