Find frequent terms in a document-term or term-document matrix.

findFreqTerms(x, lowfreq = 0, highfreq = Inf)

A character vector of terms in x which occur more or equal often than lowfreq times and less or equal often than highfreq

x

lowfreq

highfreq

times.

A DocumentTermMatrix or TermDocumentMatrix.

DocumentTermMatrix

TermDocumentMatrix

A numeric for the lower frequency bound.

A numeric for the upper frequency bound.

This method works for all numeric weightings but is probably most meaningful for the standard term frequency (tf) weighting of x.

tf

data("crude") tdm <- TermDocumentMatrix(crude) findFreqTerms(tdm, 2, 3)
