Exercise

Using position objects

Now that the position objects have been created, you can apply them to the base plot to see their effects. You do this by adding a point geom and setting the position argument to the position object.

The variables from the last exercise, posn_j, posn_d, posn_jd, and p_wt_vs_fcyl_by_fam are available in your workspace.
