Get shapefiles from ABS (via strayr and absmapsdata or via hpa.spatial and hpa.spatial.data)
get_polygon.RdGet shapefiles from ABS (via strayr and absmapsdata or via
hpa.spatial and hpa.spatial.data)
Usage
get_polygon(
name = NULL,
area = NULL,
year = NULL,
remove_year_suffix,
export_dir = tempdir(),
.validate_name,
simplify_keep = 1,
crs = NULL,
...
)Arguments
- name
A character string containing
absmapsdatafile names in[area][year]format, eg "sa42016"; "gcc2021". See full list at <https://github.com/wfmackey/absmapsdata>. Note: if name is entered, then area and year values will be ignored.- area
A character string containing the concise absmapsdata area names, eg "sa4"; "gcc". See full list at <https://github.com/wfmackey/absmapsdata>.
- year
A character string or numeric of the full source year of
absmapsdataobject, eg "2016"; 2021. See full list at <https://github.com/wfmackey/absmapsdata>.- remove_year_suffix
A logical defaulting to FALSE. If TRUE, 'strip_year_suffix' is run before returning the object, removing the '_year' suffix from variable names.
- export_dir
Path to a directory to store the desired sf object.
tempdir()by default.- .validate_name
Logical defaulting to TRUE, which checks the name input (or area year combination) against a list of available objects in the
absmapsdatapackage.- simplify_keep
The proportion of points to retain (0-1; default 1 - no simplification).
- crs
Whether to update the crs (if necessary) of the returned polygon.
- ...
Arguments passed to
rmapshaper::ms_simplify()(other thankeep).
