CreateAdjMatrix: Creates an adjacency matrix from a set of edges.

In lancour/ignition: INTEGRATION OF GENETIC ASSOCIATIONS WITH NETWORK DIFFUSION

Description

The first step in the ignition workflow (if you are using your own edge set) is to convert the edges into an adjacency matrix. This method provides a simple framework for doing so.

Usage

CreateAdjMatrix(edge.set)

Arguments

edge.set

A data frame with two columns. Each row is an interaction and each column is a gene involved in the interaction. Optionally, the data frame can additionally contain a third column containing a numeric confidence measure for each interaction. Interactions with missing or negative confidence measures are ignored.

Value

An adjacency matrix representation of the given edge set.

Examples

data(ignition.example.edges)
adj.mat = CreateAdjMatrix(ignition.example.edges)
