GeomTimelineLabel: Plot a timeline of earthquakes with labels

In perfectslumber/NOAAsignif: Visualize significant earthquake dataset from NOAA website

Description

This geom plots a time line of earthquakes with a point for each earthquake. This geom adds a vertical line to each data point with a text annotation (the location of the earthquake) attached to each line. There is an option to subset to n_max number of earthquakes, where we take the n_max largest (by magnitude) earthquakes. Aesthetics are x, which is the date of the earthquake and label which takes the location column from which annotations will be obtained. This geom is the prototype required for geom_timeline_label() function to work.

Usage

GeomTimelineLabel

Format

An object of class GeomTimelineLable (inherits from Geom, ggproto, gg) of length 5.
