events_exposure: Write storm events exposure files

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

Description

This function takes an input of locations (either a vector of county FIPS or a dataframe of multi-county FIPS, with all FIPS listed for each county) and creates a dataframe with storm listings and dates that can be merged with time series of health or other outcomes, giving the dates and exposures for all storms meeting the given storm events criteria.

Usage

events_exposure(
  locations,
  start_year,
  end_year,
  event_type,
  out_dir,
  out_type = "csv"
)

Arguments

locations	Either a vector of FIPS county codes, for county-level output, or a dataframe with columns for community identifier (commun) and associated FIPS codes (fips), for multi-county community output. See the examples for the proper format for this argument.
start_year	Four-digit integer with first year to consider.
end_year	Four-digit integer with last year to consider.
event_type	Character string with the type of event to use to identify county exposures. Options include "flood", "tornado", "wind", and "tropical_storm".
out_dir	Character string with the filepath to the directory where the data will be saved
out_type	Character string with the type of file to save to. Options are "csv" for a comma-separated file (default) and "rds" for an R object file.

Value

Writes out a directory with rain exposure files for each county or community indicated. For more on the columns in this output, see the documentation for county_rain and multi_county_rain.
