It is not clear to me how to use the
data argument in
stat_poly_eq? It looks like by default,
stat_poly_eq expects the variables in the formula X~Y to be in the user workspace... can they not be in the workspace of
data? or ideally, like the
stat_fit series, implicitely within the ggplot() call? It seems that there is a quite big difference between
stat_fit_tidy are handled, but I could not find this described somewhere?
