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.
