geom_timeline: geom_timeline

In Moonglum8/rEarthquake: rEarthquake

Description

A ggplot2 graphical function to plot a timeline of earthquakes from cleaned data. The plot indicates the magnitude of each earthquake and number of deaths.

Usage

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

Arguments

mapping	mapping
data	data
stat	stat
position	position
na.rm	na.rm
show.legend	show.legend
inherit.aes	inherit.aes
...	...

Value

ggplot2 graphical object

Aesthetics

geom_timeline understands the following aesthetics:

• x date

• y latitude

• 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

library(dplyr)
library(ggplot2)
library(lubridate)
eq_clean_data(eq_data_raw) %>% eq_location_clean() %>%
dplyr::filter(COUNTRY %in% c("USA","IRAN"))  %>%
    ggplot2::ggplot() +
    geom_timeline(aes(x = date,
                      y = COUNTRY,
                      colour = DEATHS,
                      size = EQ_PRIMARY,
                      fill = DEATHS,
                      xmin = lubridate::ymd_hm("2000-01-01",truncated = 2),
                      xmax = lubridate::ymd_hm("2016-01-01",truncated = 2)))
