Find the neighborhood of a set of nodes.

Find the neighborhood of a set of nodes.

# S4 method for network
geneNeighborhood(
  net,
  targets,
  nv = 0,
  order = length(net@time_pt) - 1,
  label_v = NULL,
  ini = NULL,
  frame.color = "white",
  label.hub = FALSE,
  graph = TRUE,
  names = FALSE
)

Arguments

net

a network object
targets

a vector containing the set of nodes
nv

the level of cutoff. Defaut to 0.
order

of the neighborhood. Defaut to `length(net@time_pt)-1`.
label_v

vector defining the vertex labels.
ini

using the ``position'' function, you can fix the position of the nodes.
frame.color

color of the frames.
label.hub

logical ; if TRUE only the hubs are labeled.
graph

plot graph of the network. Defaults to `TRUE`.
names

return names of the neighbors. Defaults to `FALSE`.

Value

The neighborhood of the targeted genes.
