Detect feedback loops in a network

Description

Detects feedback loops in a network.

Usage

findloops(mat, maxnodes, minnodes = 2)

Arguments

mat	A matrix of edge weights
maxnodes, minnodes	Maximum and minimum number of nodes permitted to be involved in the loop for it to be included in the output.

Details

Note: this has not yet been tested and may not behave as intended.

Value

A list with:

• A list of character vectors, each being a loopderived from the network

• A data.frame with one loop per row, describing

  • a character description of the involved nodes and the sign of the edges between them

  • The product of all edge weights, indicating whether it is a positive or negative feedback loop

  • The number of nodes involved

• A list of matrices, each of the same size as mat and retaining only the edges involved in the loop
