geom_timeline: geom_timeline

In marcelamu95/earthquakeGeoms:

Description

This function displays the dates of Earthquakes by presenting each Earthquake, on a straight line, as a point of varying sizes depending on their Ritcher scale value (based on the size variable). The Earthquakes are color coded by the death toll it caused (colour). If the y variable is supplied, the Earthquakes will be displayed in multiple horizontal lines, each line represnting the quakes for each Country.

Usage

geom_timeline(mapping = NULL, data = NULL, stat = "identity",
  position = "identity", na.rm = FALSE, show.legend = NA,
  inherit.aes = TRUE, ...)

Arguments

mapping	Mapping argument to the ggplot layer function.
data	A Dataframe Object containing the data to plot.
stat	Stat argument to the ggplot layer function.
position	Position argument to the ggplot layer function.
na.rm	na.rm argument to the ggplot layer function.
show.legend	show.legend argument to the ggplot layer function.
inherit.aes	inherit.aes argument to the ggplot layer function.
...	Extra Params.

Value

This function adds the lineGrobs and pointGrob into the current graphics device.
