title: 'Rvoterdistance: Voter Distance to Polling Locations and Geographic Boundaries'
version: 2.1.0
doi: 10.32614/CRAN.package.Rvoterdistance
abstract: Calculates the distance between each voter in a voter file (given lat/long
  coordinates or sf point geometries) and multiple polling or vote-by-mail drop box
  locations. Returns nearest location, k-nearest locations, or all locations within
  a distance threshold. Also computes minimum distance from voters to geographic boundaries
  such as rivers, state borders, or district lines provided as 'sf' line or polygon
  geometries. Core computation uses the Haversine formula and spherical cross-track
  distance implemented in C++ via 'Rcpp'.
