\title{Perform a pairwise count of words by id}
|
|
\usage{
|
|
pairwise_count(data, id = "line", word = "word")
|
|
}
|
|
\arguments{
|
|
\item{data}{Data frame output from \code{tm_clean()}.}
|
|
|
|
\item{id}{String to represent the id variable. Defaults to \code{"line"}.}
|
|
|
|
\item{word}{String to represent the word variable. Defaults to \code{"word"}.}
|
|
}
|
|
\value{
|
|
data frame with the following columns representing a pairwise count:
|
|
\itemize{
|
|
\item \code{"item1"}
|
|
\item \code{"item2"}
|
|
\item \code{"n"}

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