search_term_collocations: Search For Collocations

In trinker/termco: Counts of Terms and Substrings

Description

A wrapper for search_term + frequent_terms. Find words that frequently collocate with a term(s). Note that the 'term regexes are eliminated from the output of top occurring terms.

Usage

search_term_collocations(text.var, term, n = 10, ignore.case = TRUE, ...)

Arguments

text.var	A vector of character strings.
term	A regular expression(s) to search for (uses grep).
n	The number of rows to print. If integer selects the frequency at the nth row and prints all rows >= that value. If proportional (less than 0) the frequency value for the nth% row is selected and prints all rows >= that value.
ignore.case	logical. Should grep be done independent of case?
...	Other arguments passed to search_term and frequent_terms.

Value

Returns a data.frame of collocating terms and frequencies.
