That's pretty weird, because the posterior method is in the topicmodels package (see here), and you should have loaded that already to create m (LDA is also in the topicmodels packages).
Maybe your R session reset for some reason. Could you try running library(topicmodels)
again?
Nope, still not working. I cleared my environment and console and tried again but same error
It works for me:
> m = c("a text", "another text", "not very useful") %>% quanteda::dfm() %>% quanteda::convert(to="topicmodels") %>% LDA(k=2, method = "Gibbs")
Warning message:
'dfm.character()' is deprecated. Use 'tokens()' first.
> m
A LDA_Gibbs topic model with 2 topics.
> class(m)

attr(,"package")

> posterior(m)

can you paste the output of sessionInfo()
, the output of class(m)
, and the exact code you are running that produces an error?
m = c("a text", "another text", "not very useful") %>% quanteda::dfm() %>% quanteda::convert(to="topicmodels") %>% LDA(k=2, method = "Gibbs") m A LDA_Gibbs topic model with 2 topics. class(m) [1] "LDA_Gibbs" attr(,"package") [1] "topicmodels" posterior(m) Error in UseMethod("posterior") : no applicable method for 'posterior' applied to an object of class "c('LDA_Gibbs', 'LDA', 'Gibbs', 'TopicModel')"
This is the output of the above code
can you paste the output of sessionInfo()?
also, can you try reinstalling topicmodels?
words = posterior(m)$terms[topic, ] Error in UseMethod("posterior") : no applicable method for 'posterior' applied to an object of class "c('LDA_Gibbs', 'LDA', 'Gibbs', 'TopicModel')"
I'm getting an error like this. what to do? Do I have to load any more libraries?
