geom_timeline: Timeline charts

In rafaelcb/NOAA: Explore NOAA earthquake data

Description

This geom creates a timeline of events and adds it to a plot.

Usage

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

Arguments

mapping	Set of aesthetic mappings created by aes or aes_.
data	The data to be displayed. If specified and inherit.aes = TRUE (the default), it is combined with the default mapping at the top level of the plot. You must supply mapping if there is no plot mapping.
na.rm	If FALSE, the default, missing values are removed with a warning. If TRUE, missing values are silently removed.
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, the default, includes if any aesthetics are mapped. FALSE never includes, and TRUE always includes.
inherit.aes	If FALSE, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g. borders.
...	other arguments passed on to layer.

Value

A GeomTimeline layer

Examples

## Not run: eq_data %>% eq_clean_data() %>% filter(EQ_PRIMARY > 6, DATE > "2000-01-01") %>%
ggplot(aes(x = DATE, size = EQ_PRIMARY, color = DEATHS, y = COUNTRY)) +
geom_timeline()
## End(Not run)
