findFreqTerms: Find Frequent Terms

Description

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

Usage

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

Arguments

x

A DocumentTermMatrix or TermDocumentMatrix.

lowfreq

A numeric for the lower frequency bound.

highfreq

A numeric for the upper frequency bound.

Value

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

Details

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

Examples

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