geom_timeline_label: Label for NOAA Time line

In jyjek/jyjekNOAA: Plot for Analysis NOAA dataset

Description

This function add labeling the top n earthquakes, by magnitude. Default value is the top 5 earthquakes for each country specified. User can change this value n_max aesthetic.

Usage

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

Arguments

mapping	see ggplot2 layer
data	see ggplot2 layer
stat	see ggplot2 layer
position	see ggplot2 layer
na.rm	see ggplot2 layer
show.legend	see ggplot2 layer
inherit.aes	see ggplot2 layer
...	other arguments.

Aesthetics

geom_timeline_label undertands the following aesthetics (required aesthetics are in bold):

• x: recommend DATE

• label: recommend LOCATION_NAME

• magnitude: recommend EQ_PRIMARY

• y: recommend COUNTRY

• n_max: default 5. Top n earthquakes to label, sorted by magnitude.

• color

• linetype

• size

• alpha

• NOAA_thm

• GTL
