id2shp: id2shp: Retrieve vector data given ID strings

In cmarmstrong/rv: Retrieve vector data from ID strings

Description

This package downloads administrive boundaries and other vector data from Natural Earth and TIGER

Accepts a place code and returns an administrative boundary vector. This function will service place codes from rnaturalearth place names, Federal Information Processing Standard (FIPS) codes, and hierarchical administrative subdivision codes (HASC). If no names or codes are given, returns an extent for the globe in longitude/latitude.

Usage

id2shp(
  country = NULL,
  hasc = NULL,
  fips = NULL,
  cb = TRUE,
  resolution = "20m",
  buffer = 0,
  returnclass = "sp",
  scale = "large",
  ...
)

Arguments

country	A country name identified in naturalearth country names
hasc	A HASC
fips	A FIPS code
cb	Logical. Applies only to FIPS codes. If true will return a generalized resolution cartographic boundary vector, otherwise returns a higher resolution vector. Default TRUE.
resolution	The resolution if cb is TRUE. Applies only with argument ‘FIPS’. Options are 500k, 5m, and 20m for 1:500k, 1:5 million, and 1:20 million.
buffer	Integer. If greater than zero will buffer the vector data to the value of this argument. Will not work with ‘returnclass’ set to 'sf'.
returnclass	set the class of the returned geometry. Accepts a value of either ‘sf’ or ‘sp’.
scale	The scale of the vector data. Applies only with arguments ‘country’ or ‘hasc’. Options are 'small', 'medium', or 'large'.
...	Additional arguments, unused.

Details

Vector data is downloaded using rnaturalearth (place names and HASC) or tigris (FIPS codes)

Value

A vector for the administrative boundary identified by the location code
