geom_timeline_label: Label large earthquakes with annotation

In zumthor86/quakeR: Makes working with the NOAA Significant Earthquake Database easier

Description

This geom is intended to be used in conjunction with a geom_timeline layer to provide additional annotations to a timeline of earthquakes

Usage

geom_timeline_label(mapping = NULL, data = NULL,
  position = "identity", na.rm = FALSE, show.legend = NA,
  inherit.aes = TRUE, n_max = 5, ...)

Arguments

mapping	Set of aesthetic mappings created by aes() or aes_(). If specified and inherit.aes = TRUE (the default), it is combined with the default mapping at the top level of the plot. You must supply mapping if there is no plot mapping.
data	The data to be displayed in this layer. There are three options: If NULL, the default, the data is inherited from the plot data as specified in the call to ggplot(). A data.frame, or other object, will override the plot data. All objects will be fortified to produce a data frame. See fortify() for which variables will be created. A function will be called with a single argument, the plot data. The return value must be a data.frame., and will be used as the layer data.
position	Position adjustment, either as a string, or the result of a call to a position adjustment function.
na.rm	If false a warning is given when missing values are removed
show.legend	logical. Should this layer be included in the legends? NA, the default, includes if any aesthetics are mapped. FALSE never includes, and TRUE always includes. It can also be a named logical vector to finely select the aesthetics to display.
inherit.aes	If FALSE, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g. borders().
n_max	Number of points to annotate
...	Other arguments passed to layer function

Examples
