Description

This method returns a layer that contains the timeline geom with labels for earthquake locations. The color aesthetic shows the number of deaths. The size aesthetic shows the Richter scale of the earthquakes.

Usage

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

Arguments

mapping	Set of aesthetic mappings created by aes or aes_.
data	The data to be displayed in this layer, data.frame
stat	The statistical transformation to use on the data for this layer, as a string.
position	Position adjustment as a string or function.
na.rm	either TRUE or FALSe for for removing missing values with or without warning.
show.legend	TRUE or FALSE to show the legend or notlogical.
inherit.aes	TRUE or FALSE for inheriting aies
...	Additional parameters

Value

A layer containing the timeline geom with labels.
