Combine singular features into plural versions

Description

Combines a FeatureCollection of Point, LineString, or Polygon features into MultiPoint, MultiLineString, or MultiPolygon features.

Usage

lawn_combine(fc, lint = FALSE)

Arguments

fc	A data-FeatureCollection of any type.
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

Examples

# combine points
fc1 <- '{
 "type": "FeatureCollection",
 "features": [
   {
     "type": "Feature",
     "properties": {},
     "geometry": {
       "type": "Point",
       "coordinates": [19.026432, 47.49134]
     }
   }, {
     "type": "Feature",
     "properties": {},
     "geometry": {
       "type": "Point",
       "coordinates": [19.074497, 47.509548]
     }
   }
 ]
}'
lawn_combine(fc1)
