Clean subject line text prior to analysis

Description

This function processes the Subject column in a Meeting Query by applying tokenisation usingtidytext::unnest_tokens(), and removing any stopwords supplied in a data frame (using the argument stopwords). This is a sub-function that feeds into tm_freq(), tm_cooc(), and tm_wordcloud(). The default is to return a data frame with tokenised counts of words or ngrams.

Usage

tm_clean(data, token = "words", stopwords = NULL, ...)

Arguments

data	A Meeting Query dataset in the form of a data frame.
token	A character vector accepting either "words" or "ngrams", determining type of tokenisation to return.
stopwords	A character vector OR a single-column data frame labelled 'word' containing custom stopwords to remove.
...	Additional parameters to pass to tidytext::unnest_tokens().

Value

data frame with two columns:

• line

• word
