Description

Turn a segment list into an edgelist suitable for constructing an ngraph

It is up to the caller to generate the seglist. Note that isolated points will be dropped since they have no edges.

Value

An integer matrix of N rows and 2 columns

Examples

## Not run: 
library(nat)
# make a neuron with multiple subtrees
n=prune_vertices(Cell07PNs[[1]], 48L)
# Must use flatten=T if including all subtrees
sl=as.seglist(n, all = TRUE, flatten = TRUE)
c_EdgeListFromSegList(sl)
