 ### Principal component analysis
 
-The stylo2gg package is designed to work on data recorded by the stylo package. The following code shows stylo at work, measuring word frequencies among the eighty-five *Federalist Papers*, originally published pseudonymously in 1788. As called here, the stylo package limits words to those common to at least 75% of the texts (using the `culling...` argumements), saves the data in an object called `federalist_mfw`, and plots the texts based on their word usage with principal component analysis:
