Expand Geometries — expand

Expands geometries into a list of vectors of their components.

Usage

expand_geoms(x)

Arguments

x: an object of class rsgeo

Value

A list of rsgeo vectors containing each original geometry's components as a new vector.

Details

rs_MULTIPOINT expands into a vector of points
rs_LINESTRING expands into a vector points
rs_MULTILINESTRING expands into a vector of linestrings
rs_POLYGON expands into a vector of linestrings
rs_MULTIPOLYGON expands into a vector of polygons

If you wish to have a single vector returned, pass the results into flatten_geoms().

Examples

mpnts <- geom_multipoint(runif(10), runif(10), rep.int(1:5, 2))
expand_geoms(mpnts)
