15. You can use favstats to get the summary statistics within each high_BA group, and bwplot() to make boxplots. For example, what appears to be the link between homeruns and high_BA? Do teams with higher batting averages tend to hit more home runs?

favstats (homeruns ~ high_BA, data = mlb11)

densityplot (~ homeruns, groups = high_BA, data = mlb11, auto.key = TRUE)
