Summarise y values at unique/binned x — stat_summary_binstat_summary() operates on unique x or y; stat_summary_bin() operates on binned x or y. They are more flexible versions of stat_bin(): instead of just counting, they can compute any aggregate. stat_summary_bin( mapping = NULL, data = NULL, geom = "pointrange", position = "identity", ..., fun.data = NULL, fun = NULL, fun.max = NULL, fun.min = NULL, fun.args = list(), bins = 30, binwidth = NULL, bre
