findAssocs(x, terms, corlimit)
A DocumentTermMatrix
or a
TermDocumentMatrix
.
a character vector holding terms.
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.
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
.
