Download zipped data from GISCO to the cache_dir
and extract the relevant files.
Arguments
- id
A character string or numeric value with the dataset type to download, see Details. Supported values are:
"countries"."coastal_lines"."communes"."lau"."nuts"."urban_audit"."postal_codes".This argument replaces the previous (deprecated) argument
id_giscoR.
- year
A character string or numeric value with the release year of the file, see Details.
- cache_dir
A character string with a path to a cache directory. See Caching strategies section in
gisco_set_cache_dir().- update_cache
A logical value indicating whether to refresh the cached file. Defaults to
FALSE. When set toTRUE, it forces a new download.- verbose
A logical value. If
TRUEdisplays informational messages.- resolution
A character string or numeric value with the geospatial data resolution. One of:
"60": 1:60 million."20": 1:20 million."10": 1:10 million."03": 1:3 million."01": 1:1 million.
- ext
The extension of the file or files to download. Available formats are
"shp","geojson","svg","json"and"gdb". See Details.- recursive
recursiveis no longer supported. It will never perform recursive extraction of child.zipfiles. This is the case forshp.zipinside the top-level.zip, which will not be unzipped.- ...
Ignored. The argument
id_giscoR() is captured via
...and redirected toidwith a warning.
Details
Some arguments only apply to a specific value of "id". For example
"resolution" is ignored for values "communes", "lau",
"urban_audit" and "postal_codes".
See available years in the corresponding functions:
The usual extensions used across giscoR are "gpkg" and "shp",
but other formats are already available on GISCO. After a bulk download, you
may need to adjust the default ext value in the corresponding function
to connect it with the downloaded files (see Examples).
