geom_timeline_label: The geom_timeline_label function
In simongarisch/R-Capstone-NOAA: Coursera R Capstone project

Used in conjunction with GeomTimelineLabel. See the layout contained within the course materials p.g. 452 Note that you should run geom_timeline first such that we have our points to annotate This geom will then look to annotate the largest n_max earthquakes with a vertical line and a label tagging these points. Given that we are only annotating n_max earthquakes we sort the data by magnitude and select the largest before plotting.

n_max

An integer (default = 5) indicating the maximum number of earthquakes to display.
