target.help: Transform a list of Pathway IDs into a binary matrix.

Description

This function is an internal function used to transform the given list of $p$ (one vector of pathway IDs per gene) groups into a binary matrix.

Usage

target.help(genes)

Arguments

genes

List of $p$ items. Each item is the vector of Pathway IDs a gene belongs to.

Value

A $p x p$ binary matrix: the coefficient (i,j) is 1 if genes i and j belong to a common pathway and 0 otherwise. This is an internal function called by for example targetG.
