Description

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

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

Arguments

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

Run this code
# NOT RUN {
data("crude")
tdm <- TermDocumentMatrix(crude)
