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.
