  inherit.aes = TRUE, ...)

Arguments

mapping	mapping
data	data
stat	stat
position	position

Aesthetics

geom_timeline understands the following aesthetics:

• x DATE

• y Countries

• xmin minimum date for earthquakes

• xmax maximum date for earthquakes

• size used to size shape based on magnitude of earthquake eg EQ_PRIMARY

• fill used to colour shape based on number of deaths eg DEATHS

• colour used to colour shape based on number of deaths eg DEATHS

Examples

## Not run: 
library(ggplot2)
dmin = as.Date("2000-01-01", format="%Y-%m-%d")
dmax = as.Date("2017-01-01", format="%Y-%m-%d")
ggplot(df) +
geom_timeline(aes(x=DATE,
                  colour=DEATHS,
                  size=RITCHER,
                  fill=DEATHS,
                  xmin=dmin,
                  xmax=dmax)
             )
