PWAmat: A function to compute the probe to KEGG pathway incidence matrix.

Description

For a given chip we compute the mapping from probes to KEGG pathways.

Usage

PWAmat(data)

Arguments

data

The name of the chip for which the incidence matrix should be computed.

Value

A matrix containing zero or one, depending on whether the probe (row) is in a pathway (column).

Details

Not much to say, just find which probes are in which pathways and return the incidence matrix, with pathways as rows and probes as columns.

It would be nice to be able to specify a set of probes to use, so that one does not do perform the calculations using all probes if they are not of interest.
