geom_timeline: geom_timeline

In tcoopermont/eqtools: Earthquake Tools

Description

This function generates a timeline plot with years as y axis and individual earthquake dates as points on the x axis.

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 <e2><80><98>aes<e2><80><99>. Can be inherited from upper levels of the plot.
data	The data to be displayed in this layer. Can be NULL, data.frame or function
stat	The statistical transformation to use on the data for this layer
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 <e2><80><98>FALSE<e2><80><99>, the default, missing values are removed with a warning. If <e2><80><98>TRUE<e2><80><99>, missing values are silently removed.
inherit.aes	If <e2><80><98>FALSE<e2><80><99>, overrides the default aesthetics, rather than combining with them.
...	other arguments passed on to <e2><80><98>layer<e2><80><99>.

Details

: aes parameters act similar to 'geom_point'

• x: a Date object

• y: single integer or a factor. (points will be grouped by y) example: COUNTRY

• xmin: Date example 1999-1-1

• xmax: Date example 2015-12-31

• size: numeric the data field to base size of point on

Examples

## Not run: 
ggplot(quakesFiltered,aes(x = DATE, y = COUNTRY,
        xmin = as.Date("2000-1-1","%Y-%m-%d"),
        xmax = as.Date("2015-12-31","%Y-%m-%d"),
        )) +
 geom_timeline(aes(size = EQ_PRIMARY))

## End(Not run)
