R Documentation

returns additional information regarding the nodes of networks X and Y (original and augmented)

Description

This function returns some additional information regarding the nodes of networks X and Y such as the reachability of nodes in networks X to the augmented nodes of network Y.

Usage

info_node(g1,g2,taxnames, maxnode, maxdistance)

Arguments

`g1`	the original network X
`g2`	the augmented network Y with additional nodes (all the original nodes from X must be present in the augmented network Y)
`taxnames`	the taxon name of the nodes added to the original graph (default: we select all nodes that are not in g1)
`maxnode`	the maximum number of augmented nodes in network Y to take into account (default=0, no maximum number of augmented nodes to take into account. The augmented nodes are sorted by distance to the investigated node pairs by the algorithm.)
`maxdistance`	the maximum search distance to the added nodes in network Y (default=0, no maximum distance for augmented nodes to take into account)

Value

This function return information about the reachability of each node such as : reach_count(number of reachable augmented nodes), reach_max_dist (maximal distance to an augmented node), reach_min_dist (minimal distance to an augmented node), reach_mean_dist (mean distance to augmented nodes)
