graph |
The input graph.
|
root |
Numeric vector, usually of length one. The root vertex, or root
vertices to start the search from.
|
mode |
For directed graphs specifies the type of edges to follow.
‘out’ follows outgoing, ‘in’ incoming edges. ‘all’
ignores edge directions completely. ‘total’ is a synonym for
‘all’. This argument is ignored for undirected graphs.
|
unreachable |
Logical scalar, whether the search should visit the
vertices that are unreachable from the given root vertex (or vertices). If
TRUE , then additional searches are performed until all vertices are
visited.
|
restricted |
NULL (=no restriction), or a vector of vertices
(ids or symbolic names). In the latter case, the search is restricted to the
given vertices.
|
order |
Logical scalar, whether to return the ordering of the vertices.
|
rank |
Logical scalar, whether to return the rank of the vertices.
|
father |
Logical scalar, whether to return the father of the vertices.
|
pred |
Logical scalar, whether to return the predecessors of the
vertices.
|
succ |
Logical scalar, whether to return the successors of the
vertices.
|
dist |
Logical scalar, whether to return the distance from the root of
the search tree.
|
callback |
If not NULL , then it must be callback function. This
is called whenever a vertex is visited. See details below.
|
|
Additional argument to supply to the callback function.
|
rho |
The environment in which the callback function is evaluated.
|
neimode |
This argument is deprecated
from igraph 1.3.0; use mode instead.
