Usage
divisions(resolution = "500k", year = NULL, ...)
Arguments
resolution |
The resolution of the cartographic boundary file. Defaults to '500k'; options include '5m' (1:5 million) and '20m' (1:20 million). |
year |

Additional Arguments
Additional arguments that can be passed in ... are:
-

progress_barIf set toFALSE, do not display download progress bar (helpful for R Markdown documents). Defaults toTRUE. -
keep_zipped_shapefileIf set toTRUE, do not delete zipped shapefile (stored in temporary directory orTIGRIS_CACHE_DIRdepending on the configuration of global option"tigris_use_cache"). Defaults toFALSE. -
refreshWhether to re-download cached shapefiles (TRUEorFALSE) . The default is eitherFALSEor 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_byGeometry 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_bywill be returned.
