textplot_influence raises error

[cschwem2er]

Hi,

this is probably due to the affinity textmodel still being work in progress, but with the latest quanteda build, textplot_influence() raises an error for the example from manual:

fitted <- textmodel_affinity(data_dfm_lbgexample, y = c("L", NA, NA, NA, "R", NA))
pred <- predict(fitted)

> textplot_influence(fitted)
Error in textplot_influence.default(fitted) : 
  textplot_influence() only works on affinity_influence, summary_affinity_influence objects.
> textplot_influence(pred)
Error in textplot_influence.default(pred) : 
  textplot_influence() only works on affinity_influence, summary_affinity_influence objects.

Or am I using this in the wrong way?

The example seems to work fine on my Mac. As you asked the question about textplot_network() today as well, I assume you have the latest dev version of quanteda installed?

fitted <- textmodel_affinity(data_dfm_lbgexample, y = c("L", NA, NA, NA, "R", NA))
pred <- predict(fitted)
pred

but the problem is not that textmodel_affinity() doesn't work, its only the plot.

[stefan-mueller]

Sorry, my fault. Thought you had a problem with textmodel_affinity(), missed the textplot_influence() part. Now I get the same error as you. An example in the manual of textplot_influence() would be good indeed.
