Counting user types

Counts are the essential summary for categorical data. Since text is categorical, it's important to get comfortable computing counts. The twitter_data is composed of complaints and non-complaints, as indicated by the complaint_label column, and also includes a column indicating whether or not the user is verified (i.e., they have been confirmed by Twitter to be who they say they are) called usr_verified. Note that column is of type <lgl>, meaning logical. Do verified users complain more?
