R: Find Frequent Terms

findFreqTerms {tm} | R Documentation

## 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.

### Details

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

### 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.

### Examples

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