Determine if specified vertices of a network have any edges (are not isolates)

Returns a logical value for each specified vertex, indicating if it has any incident (in or out) edges. Checks all vertices by default

Usage

has.edges(net, v = seq_len(network.size(net)), ...)

# S3 method for class 'network'
has.edges(net, v = seq_len(network.size(net)), ...)

Arguments

net

a network object to be queried

v

integer vector of vertex ids to check

...

additional arguments to methods

Value

returns a logical vector with the same length as v, with TRUE if the vertex is involved in any edges, FALSE if it is an isolate.
