geom_timeline: Function to plot earthquakes timelines

In danielfsilva88/quakeTools: Functions To Clean And Visualize Earthquakes Data

Description

This function receives the ggplot2 parameters plus the Geom Timeline to add the earthquakes timeline layer in a ggplot2 object

Usage

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

Arguments

mapping	Set of aesthetic mappings created by aes() or aes_().
data	The data to be displayed in this layer.
stat	Previous calculation to prepare dataframe to be plotted
position	Position adjustment. Could be 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, the default, incldes if any aesthetics are mapped. False never includes, and TRUE always includes.
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. This is most usefule for helper functions that define both data and aesthetics and shouldn't inherit behavior from the default plot specification, e.t. borders.
...	Other arguments passed on layer like color = "red" or size = 3.

Value

The layer containing the elements created with Geom GeomTimeline
