Usage

tm_freq(data, token = "words", stopwords = NULL, keep = 100, return = "plot")

Arguments

data	A Meeting Query dataset in the form of a data frame.
token	A character vector accepting either "words" or "ngram", determining type of tokenisation to return.
stopwords	A character vector OR a single-column data frame labelled 'word' containing custom stopwords to remove.
keep	A numeric vector specifying maximum number of words to keep.
return	String specifying what to return. This must be one of the following strings: "plot" "table" See Value for more information.

A different output is returned depending on the value passed to the return argument:

• "plot": 'ggplot' object. A circular bar plot.

• "table": data frame. A summary table.
