In this screencast tutorial, Pat Schloss shows how you can use the lag function from the dplyr R package to calculate a rolling or moving average of lamb prices from his local livestock auction. Motivated by a desire to smooth noisy data, he compares the rolling average to the output of geom_smooth to plot the seasonal trends in different weight classes of lamb. He demonstrates these concepts by live coding in R with RStudio. He then turns viewers loose to work through several activities to answer related questions.
