nt.connect function

Check the connectivity of a given network

A function to check the connectivity of a given network.

Arguments

• nt: A SpatialLines or SpatialLinesDataFrame object.

nt.connect(nt)

Details

In this function, all the nodes are traversed, and classified dynamically via a rule, that any pair of different nodes fall into a same category if they could be reached from each other. A map will be plotted spontaneously with differet categories (i.e. self-connected parts) in distinct colors. Finally, the self-connected part with the most nodes will be returned as a new SpatialLinesDataFrame object.
