Usage

distance_near_eachother(lon, lat, distance, or_tied = FALSE)

Arguments

lon: longitude
lat: latitude
distance: distance between points in miles to check
or_tied: if TRUE, checks if less than or equal to distance, otherwise if less than

Value

logical vector the length of lon or lat, telling if the point is within distance of any other point in list for example, which sites have residents that might also be near others sites?

Examples

mapfast(testpoints_500[distance_near_eachother(
  lon = testpoints_500$lon, 
  lat = testpoints_500$lat, 
  3.1), ], radius = 3.1)
