geom_timeline_label: Plot a timeline of earthquake with annotations

In Liddlle/capstone: Analyzing NOAA earthquake dataset

Description

Geom for plotting a time line of earthquakes ranging from xmin to xmaxdates with a point for each earthquake. Additionally, this geom adds a vertical line to each data point with a text annotation (e.g. the location of the earthquake) attached to each line.

Usage

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

Arguments

mapping	Set of aesthetic mappings created
data	The data to be displayed
stat	The statistical transformation to use on the data for this layer, as a string.
position	Position adjustment, either as a string, or the result of a call to a position adjustment function.
show.legend	logical. Should this layer be included in the legends?
na.rm	If FALSE, the default, missing values are removed with a warning. If TRUE, missing values are silently removed.
inherit.aes	If FALSE, overrides the default aesthetics, rather than combining with them.
...	Other arguments passed on to the layer. it can be used to set an aesthetic to a fixed value.

Value

This function returns a timeline plot with annotations
