rootpoints | R Documentation |
rootpoints
returns the root point(s) (one per tree, often
the soma).
branchpoints
returns the branch points.
endpoints
returns the end points (aka leaf nodes); the
root point will be returned if it also a leaf node.

A neuron may have multiple subtrees and therefore multiple roots. At
present there is discrepancy between the *.neuron
and
*.igraph
methods. For neuron
s we return the node indices, for
igraph
/ngraph
objects the node identifiers (aka
names/PointNo)
branchpoints.neuron
returns a list if more than one subtree
is specified
FIXME Raw indices (in range 1:N) of vertices when x
is a
neuron, integer point identifier (aka PointNo) otherwise.
