Description

RcppParallel version of st_distance

Usage

st_dist_rcpp(x, y = x, unit = "mi")

Arguments

x	Object of class sf/sfc or a matrix of coordinates. If a matrix of coordinates, use column order from st_coordinates().
y	Optional. Object of class sf/sfc or a matrix of coordinates. If a matrix of coordinates, use column order from st_coordinates(). If not included, x is used.
unit	Either "mi", "km", or "m". Sets the output distance.

Value

Matrix of distances of dimension n_x by n_y.

Examples

library(sf)
nc <- st_read(system.file("shape/nc.shp", package="sf"))
st_dist_rcpp(nc[1:3,])

nc_long <- nc[rep(seq_len(nrow(nc)), 5), ]
sf::st_distance(nc_long)
st_dist_rcpp(nc_long)
