\title{Perform a Word or Ngram Frequency Analysis and return a Circular Bar

Plot}

\usage{
|
|
tm_freq(data, token = "words", stopwords = NULL, keep = 100, return = "plot")
|
|
}
|
|
\arguments{
|
|
\item{data}{A Meeting Query dataset in the form of a data frame.}
|
|
|
|
\item{token}{A character vector accepting either \code{"words"} or \code{"ngram"},
|
|
determining type of tokenisation to return.}
|
|
|
|
\item{stopwords}{A character vector OR a single-column data frame labelled
|
|
\code{'word'} containing custom stopwords to remove.}
|
|
|
|
\item{keep}{A numeric vector specifying maximum number of words to keep.}
|
|
|
|
\item{return}{String specifying what to return. This must be one of the
|
|
following strings:
|
|
\itemize{
|
|
\item \code{"plot"}
|
|
\item \code{"table"}
|
|
}
|
|
|
|
See \code{Value} for more information.}
|
|
}
|
|
\value{
|
|
A different output is returned depending on the value passed to the \code{return}
|
|
argument:
|
|
\itemize{
|
|
\item \code{"plot"}: 'ggplot' object. A circular bar plot.
|
|
\item \code{"table"}: data frame. A summary table.

\description{
|
|
Generate a circular bar plot with frequency of words / ngrams.
|
|
This function is used within \code{meeting_tm_report()}.
|
|
}
|
|
\details{
|
|
This function uses \code{tm_clean()} as the underlying data wrangling function.
|
|
There is an option to remove stopwords by passing a data frame into the
|
|
\code{stopwords} argument.
