tfidf4dtm(dtm, normalize = TRUE, fun = log2, adjust = TRUE,
  force = FALSE)

Arguments

dtm	an object of class DocumentTermMatrix rappresenting a DTM, in particular, with documents as row.
normalize	(lgl) if TRUE (default) the weights are normalized wrt documents, i.e. row_sum equals 1 for every row.
fun	The weighting function for the ratio of document-frequencies.
adjust	If TRUE (default) adds 1 to the denominator (i.e., the sum of the frequencies of a term into the corpora) to avoid the risk it happen to be zero.
force	(lgl) if TRUE (default is FALSE) the function works also for simple_triplet_matrix which are not DocumentTermMatrix
