In Rvoterdistance: Calculates the Distance Between Voter and Multiple Polling Locations

Description

Given a set of lat-long coordinates for each voter, and a set of coordinates for all drop boxes or polling locations; this function returns a dataframe length data1 (usually voter file), including haversine, mile, and kilometer distance output, as well as any other data2 variables (perhaps address).

Usage

smorgesboard(data1, data2 , lat_long1_char, lat_long2_char)

Arguments

data1	Dataset, probably a voter file, including lat/long coordinates
data2	Dataset, probably of drop box locations/polling locations, including lat/long coordinates
lat_long1_char	Character vector, latitude/longitude column names found in data1
lat_long2_char	Character vector, latitude/longitude column names found in data2

Value

A data frame of length data1, with all columns from data2 and distance_haversine, distance_mile, and distance_km appended.
