I try to fit a LDA model to a TermDocumentMatrix with the topicmodels package... but R says:
> Error in LDA(TDM, k = k, method = "Gibbs", control = list(seed = SEED, : > x is of class “TermDocumentMatrix”“simple_triplet_matrix” > class(TDM) > [1] "TermDocumentMatrix" "simple_triplet_matrix" I try to use a matrix... but don't work: > MAT <- as.matrix(TDM) > Error in LDA(MAT, k = k, method = "Gibbs", control = list(seed = SEED, : > x is of class “matrix” The help say is correct to use a DocumentTermMatrix: > Arguments > x Object of class "DocumentTermMatrix" Can anyone help me?
