21.27 Word Clouds

We can generate a word cloud as an effective alternative to providing a quick visual overview of the frequency of words in a corpus.

The (Fellows 2018) package provides the required function.

set.seed(123)
wordcloud(names(freq), freq, min.freq=40)

Notice the use of base::set.seed() only so that we can obtain the same layout each time—otherwise a random layout is chosen, which is not usually an issue.
