map_event_exposure: Map county-level exposure based on reported events

In hurricaneexposure: Explore and Map County-Level Hurricane Exposure in the United States

Description

Map counties as "exposed" or "unexposed" based on the criterion that the county had an event listing of a specified type in the NOAA Storm Events database. For more information on the underlying data, see the helpfile for the storm_events dataset.

Usage

map_event_exposure(storm_id, event_type, add_track = TRUE)

Arguments

storm_id	Character vector with the storm for which to map events (e.g., "Katrina-2005")
event_type	Character string with the type of event to use to identify county exposures. Options include "flood", "tornado", "wind", and "tropical_storm".
add_track	TRUE / FALSE of whether to add the storm's track to the map. The default is TRUE.

Value

A map showing whether eastern US counties were exposed or unexposed to a specific storm based on event listings.

Note

Note that flood events are not available for any year before 1996.
