geom_timeline: Make time line points

In piavat/eqPlotc5: Plot Earthquake Timelines and Maps

Description

This function makes plot time line of earthquakes in selected time range with a point for each earthquake. Optional aesthetics include color, size, and alpha (for transparency). The xaesthetic is a date and an optional y aesthetic is a factor indicating some stratification in which case multiple time lines will be plotted for each level of the factor (e.g. country).

Usage

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

Arguments

mapping	List of aesthetic created by aes() to use for plot.
data	The data to be displayed in this layer. NULL, the default, is the data inherited from the plot data as specified in the call to ggplot().
stat	The statistical transformation to use on the data for this layer, as a string.
position	Position adjustment.
na.rm	If FALSE, the default, missing values are removed with a warning. If TRUE, missing values are silently removed.
show.legend	Logical. Should this layer be included in the legends? NA, the default, includes if any aesthetics are mapped.
inherit.aes	Will aesthetics be inherited (TRUE/FALSE). If FALSE, overrides the default aesthetics, rather than combining with them.
...	Other arguments passed on to layer.

Value

PointsGrob object.
