Error from stemming words (stem_word function)

When you stem words with stem_word function, you might see error that looks like this.

Error in mutate_impl(.data, dots) : Evaluation error: 'wordstem' is not an exported object from 'namespace:quanteda'.

This is a bug in exploratory R package bundled with Exploratory 4.2. We are going to fix this in the next release.
Meanwhile, you can work it around by calling quanteda::char_wordstem function instead, like the following screenshot.
