Description Usage Arguments Value See Also Examples
Takes a set of data-Point's and returns a convex hull polygon. Internally, this uses the convex-hull module that implements a Monotone chain hull
1 | lawn_convex(input, lint = FALSE)
|
input |
Input points in a data-FeatureCollection. |
lint |
(logical) Lint or not. Uses geojsonhint. Takes up increasing
time as the object to get linted increases in size, so probably use by
default for small objects, but not for large if you know they are good
geojson objects. Default: |
a convex hull data-Polygon
