In Programming with R, Addressing Data, there is a line of code that shows the class of dat:
which is a "data.frame". Maybe just for completeness, it would be worth mentioning that when subsetting by column, the class of what we get changes. For example, for dat$Gender
class(dat$Gender) is "character".

As in #295, please feel free to send a PR. Your suggestion makes sense, so I'd be happy to review a specific "implementation" / addition to the lesson :-)
