In riverconn: Fragmentation and Connectivity Indices for Riverscapes

Calculates average upstream/downstream or combined distance between each couple of reaches

Description

Calculates average upstream/downstream or combined distance between each couple of reaches

Usage

set_B_directionality(
  graph,
  dir_distance_type = "symmetric",
  field_B = "length"
)

Arguments

graph	an object of class igraph. Can be both directed or undirected.
dir_distance_type	how directionality in B_ij calculations is dealt with: "symmetric" (i.e. undirected graph) or "asymmetric" (i.e. directed graph). See details.
field_B	the 'graph' edge attribute to be used to calculate the distance. Default is "length".

Value

an object of class 'igraph' with the upstream/downstream/total distances stored as edges attributes.
