geojson object or path to geojson file. If a file path, <code>sys</code>
must be true

data

command

should the output be forced to be a FeatureCollection (or
Spatial*DataFrame) even if there are no attributes? Default <code>TRUE</code>.
FeatureCollections are more compatible with rgdal::readOGR and
geojsonio::geojson_sp. If FALSE and there are no attributes associated with
the geometries, a GeometryCollection (or Spatial object with no dataframe)
will be output.

force_FC

Should the system mapshaper be used instead of the bundled mapshaper? Gives
better performance on large files. Requires the mapshaper node package to be installed
and on the PATH.

Apply a mapshaper command string to a geojson object

Edit and simplify 'geojson', 'Spatial', and 'sf'
objects. This is wrapper around the 'mapshaper' 'JavaScript' library
by Matthew Bloch <https://github.com/mbloch/mapshaper/> to perform
topologically-aware polygon simplification, as well as other
operations such as clipping, erasing, dissolving, and converting
'multi-part' to 'single-part' geometries. It relies on the
'geojsonio' package for working with 'geojson' objects, the 'sf'
package for working with 'sf' objects, and the 'sp' and 'rgdal'
packages for working with 'Spatial' objects.
