urban_areas {tigris} | R Documentation |
Download an urban areas shapefile into R
Description
Urban areas include both "urbanized areas," which are densely developed areas with a population of at least 50,000, and "urban clusters," which have a population of greater than 2,500 but less than 50,000. For more information, please see the link provided.
Usage
urban_areas(cb = FALSE, year = NULL, criteria = NULL, ...)
Arguments
cb |
If cb is set to TRUE, download a generalized (1:500k) cartographic boundary file. Defaults to FALSE (the most detailed TIGER/Line file). |
year |
the data year; defaults to 2022 |
criteria |
If set to "2020" and the year is 2020, will download the new 2020 urban areas criteria. Not available for cartographic boundary shapefiles / other years at the moment. |
... |
arguments to be passed to internal function |
Additional Arguments
Additional arguments that can be passed in ...
are:
-
class
Desired class of return object:"sf"
(the default) or"sp"
. sp classes should be considered deprecated as of tigris version 2.0, but legacy support is still available. -
progress_bar
If set toFALSE
, do not display download progress bar (helpful for R Markdown documents). Defaults toTRUE
. -
keep_zipped_shapefile
If set toTRUE
, do not delete zipped shapefile (stored in temporary directory orTIGRIS_CACHE_DIR
depending on the configuration of global option"tigris_use_cache"
). Defaults toFALSE
. -
refresh
Whether to re-download cached shapefiles (TRUE
orFALSE
) . The default is eitherFALSE
or the value of global option"tigris_refresh"
if it is set. Specifying this argument will override the behavior set in"tigris_refresh"
global option. -
filter_by
Geometry used to filter the output returned by the function. Can be an sf object, an object of classbbox
, or a length-4 vector of formatc(xmin, ymin, xmax, ymax)
that can be converted to a bbox. Geometries that intersect the input tofilter_by
will be returned.
