Path decomposition

Start in the middle, and build the 'path-link-vertex' table.

Paths.

Arguments

x

input object

...

arguments passed to methods

ids

object id, one for each object in the sfc

Value

data frame of path identity and properties

Details

Paths have properties of their type, their number of vertices, their geometric dimension and which object they occur in.

sc_coord for the coordinates part of the model, sc_object for the features, and PATH for the full model.
