Calculates equivalent passability based on graph directionality and directionality type

Description

Calculates equivalent passability based on graph directionality and directionality type

Usage

set_c_directionality(
  graph,
  dir_fragmentation_type = "symmetric",
  pass_confluence = 1,
  pass_u = "pass_u",
  pass_d = "pass_d"
)

Arguments

graph	an object of class igraph. Can be both directed or undirected.
dir_fragmentation_type	how directionality in c_ij calculations is dealt with: "symmetric" (i.e. undirected graph) or "asymmetric" (i.e. directed graph)
pass_confluence	a value in the range [0,1] that defines the passability of confluences (default is 1).
pass_u	the 'graph' edge attribute to be used as upstream passability. Default is "pass_u".
pass_d	the 'graph' edge attribute to be used as downstream passability. Default is "pass_d".

Value

an object of class 'igraph' with the equivalent passability stored in the edge attribute 'pass_eq'
