Matt Parker will talk about wrangling data using the plyr package and will compare the methods to how you might do the same thing using base functions. If you have a specific example you'd like to see, preferrably working already in plyr or base, please contact Matt by June 7th.

    Another top notch presentation, this time showing several ways to perform analyses by groups. I like the ease with which a model can be fitted separately to each of several groups.
