In kmcd39/geox: auxiliary functions for geographic data.

These functions use non-tigris queries that might be more specialized, but I like for my personal convenience. get.NHPN

Description

Get National Highway Planning Network highway data. NOTE: NHPN data is better for generating rays, but I now think using tigris::roads is better for many other uses.

Usage

get.NHPN(
  sfx = NULL,
  dropbox.dir = Sys.getenv("drop_dir"),
  subdir = "shapefiles/nhpn/"
)

Arguments

sfx	if not NULL, an sf object to use to crop hwy data. Will also transform hwys to match CRS
dropbox.dir, subdir	concatenated to get to nhpn data
