findFreqTerms: Find Frequent Terms

Description

Find frequent terms in a term-document matrix.

Usage

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

Arguments

object

A term-document matrix.

lowfreq

An integer for the lower frequency bound.

highfreq

An integer for the upper frequency bound.

Value

• A character vector of terms in object 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 object.

Examples

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