nd.nfd {NetworkDistance}

Network Flow Distance

Description

Network Flow Distance

Usage

nd.nfd(
  A,
  order = 0,
  out.dist = TRUE,
  vect = seq(from = 0, to = 10, length.out = 1000)
)

Arguments

A

a list of length N containing adjacency matrices.

order

the order of Laplacian; currently only 0 and 1 are supported.

out.dist

a logical; TRUE for computed distance matrix as a dist object.

vect

a vector of parameters t whose values will be used.

Value

a named list containing

D

an (N\times N) matrix or dist object containing pairwise distance measures.
