geom_timeline_label: Plot a labeled timeline of earthquakes within a given time...

In perfectslumber/NOAAsignif: Visualize significant earthquake dataset from NOAA website

Description

This function utilizes the GeomTimelineLable geom to plot the earthquake events with labels (location of the earthquake). There is an option to subset to n_max number of earthquakes, where we take the n_max largest (by magnitude) earthquakes. In the provided example, the color aes reflects the number of deaths resulted from the earthquake with grey ones indicating no data available. The size aes reflects the magnitude of the eqrthquake. The X-axis is the date. n_max can be customized, the default value is 5.

Usage

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

Arguments

mapping	Aesthetic mappings created by aes
data	Dataset from NOAA website
stat	The statistical transformation used
position	Position adjustment function
na.rm	Remove the NA values from the data frame
show.legend	Legend
inherit.aes	Default aesthetics
...	Other arguments

Value

The labeled timeline plot.

Examples

#Pick data points ranging from date \code{xmin} to \code{xmax} from the cleaned dataset to plot
           ## Not run: eq_tidy_data <- eq_clean_data(eq_download_data())
           ## Not run: xmin <- as.Date("1999-01-01")
           ## Not run: xmax <- as.Date("1999-07-01")
           ## Not run: sample_data <- filter(eq_tidy_data, DATE >= xmin & DATE <= xmax)
           ## Not run: ggplot(sample_data,
                   aes(x = DATE, label = LOCATION, size = EQ_PRIMARY, fill = DEATHS,
                   color = DEATHS, n_max = 4)) +
                   geom_timeline_label() +
                   theme_minimal()
## End(Not run)
