This is the second day of the Introduction to R mini course. Yesterday we covered the basics of R, ending with our most commonly used data structure: the data frame. Today we'll learn how to manipulate data frames so that they're ready to be plotted. We'll end by plotting some actual linguistic data (made available by Joe Fruehwald). Can't get enough of plotting linguistic data? Step up your game by tackling the two plotting challenges in the ddplyr section.
