Description Usage Arguments Value See Also Examples

Dissolves a FeatureCollection of polygons based on a property. Note that multipart features within the collection are not supported

1	lawn_dissolve(features, key, lint = FALSE)

`features`	A data-FeatureCollection<(data-Polygon)>
`key`	(character) The property on which to filter
`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: `FALSE`

a data-FeatureCollection<(data-Polygon)> containing the dissolved polygons

Other assertions: lawn_circle(), lawn_tesselate()
