pairwise_count: Perform a pairwise count of words by id

Description

This is a 'data.table' implementation that mimics the output of pairwise_count() from 'widyr' to reduce package dependency. This is used internally within tm_cooc().

Usage

pairwise_count(data, id = "line", word = "word")

Value

data frame with the following columns representing a pairwise count:

• "item1"

• "item2"

• "n"

Arguments

data

Data frame output from tm_clean().

id

String to represent the id variable. Defaults to "line".

word

String to represent the word variable. Defaults to "word".
