reverse_edges: Reverse Edge Direction

In cograph: Analysis and Visualization of Complex Networks

Reverse Edge Direction

Description

Transposes the weight matrix, so every arc runs the other way. TNA users reach for this to look at where transitions came from rather than where they went.

Usage

reverse_edges(x, keep_format = FALSE, directed = NULL)

Arguments

x	Network input.
keep_format	Logical. Return the input format when TRUE.
directed	Logical or NULL. If NULL (default), auto-detect.

Value

A cograph_network with every edge reversed, or the input format when keep_format = TRUE. An undirected network is returned unchanged, with a cograph_no_effect warning.

                0, 0, .7,
                0, 0, 0), 3, 3, byrow = TRUE)
rownames(adj) <- colnames(adj) <- c("A", "B", "C")

reverse_edges(adj)
