View source: R/geom_timeline_label.R

Description

geom_timeline_label works best when used with geom_timeline, labeling the top n earthquakes, by magnitude, with a specified label field. By default, the labels are for the top 5 earthquakes for each country specified, however, the user may adjust this with the n_max aesthetic.
