map_distance_exposure: Map counties with distance exposure

In geanders/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 storm came within a given distance (specified by dist_limit) of the county's population mean center.

Usage

map_distance_exposure(storm, dist_limit, add_track = TRUE)

Arguments

storm	Character string giving the name of the storm to plot (e.g., "Floyd-1999")
dist_limit	Maximum distance, in kilometers, of how close the storm track must come to the county's population mean center to classify the county as "exposed" to the storm.
add_track	TRUE / FALSE of whether to add the storm's track to the map. The default is TRUE.

Value

Plots a map showing whether eastern US counties were exposed or unexposed to a specific storm based on a distance criterion.
