geom_timeline_label: Create Timeline Lablels

In ctaber/NOAA: Turn NOAA Data Into Earthquake Visualizations

Description

This function creates a new geom that can build on geom_timeline and add labels to the top n biggest earthqakes by magnitude

Usage

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

Arguments

mapping	defaults to NULL
data	defaults to NULL, unless data passed in
stat	defautls to 'identity'
position	defautls to 'identity'
na.rm	defaults to FALSE, do not remove NAs
show.legend	defaults to NA
inherit.aes	defaults to TRUE
...	takes additional arguments

Details

Create a new geom called geom_timeline_label that is used to plot relevant top_n labels on geom_timeline

Value

Returns a ggplot object

Examples

## Not run: data %>%
    ggplot() +
    geom_timeline(aes(
        x = DATE,
        y = COUNTRY,
        fill = TOTAL_DEATHS,
        size = EQ_PRIMARY)) +
    geom_timeline_label(aes(
        x = DATE,
        y = COUNTRY,
        magnitude = EQ_PRIMARY,
        label = LOCATION_NAME
        ,n_max=3 #number of lables to show))

## End(Not run)
