findAssocs {tm} | R Documentation

## Find Associations in a Term-Document Matrix

### Description

Find associations in a document-term or term-document matrix.

### Usage

    ## S3 method for class 'DocumentTermMatrix'
    findAssocs(x, terms, corlimit)
    ## S3 method for class 'TermDocumentMatrix'
    findAssocs(x, terms, corlimit)

### Arguments

`x` | A `DocumentTermMatrix` or a `TermDocumentMatrix`.
`terms` | a character vector holding terms.
`corlimit` | a numeric vector (of the same length as `terms`; recycled otherwise) for the (inclusive) lower correlation limits of each term in the range from zero to one.

### Value

A named list. Each list component is named after a term in `terms` and contains a named numeric vector. Each vector holds matching terms from `x` and their rounded correlations satisfying the inclusive lower correlation limit of `corlimit`.

### Examples

    data("crude")
    tdm <- TermDocumentMatrix(crude)
    findAssocs(tdm, c("oil", "opec", "xyz"), c(0.7, 0.75, 0.1))
