Description
Grow a set of nodes into its first order neighborhood.
Usage
1
grow_nodes(graph, nodes)
Arguments
graph
The SemMed graph
nodes
A vertex sequence (igraph.vs) of nodes to be grown
Details
grow_nodes obtains the set of immediate neighbors of the
supplied nodes using igraph::ego. Unlike ego,
grow_nodes flattens the result from a list to an ordinary
vertex sequence and removes the original search nodes.
Value
A vertex sequence of nodes in the neighborhood
(not including the original nodes)
See Also
find_nodes for filtering out irrelevant
nodes from this set.
Examples

data(g_mini)
node_cortisol <- find_nodes(g_mini, name = "hypercortisolemia")
nbrs <- grow_nodes(g_mini, node_cortisol)
