A function that groups probe ids by LocusLink ids

Description

This function takes the name of a platform specific annotation data package (e. g. an Affymetrix chip) and returns a list of vectors of character string with LocusLink ids as the names of the lists of vectors and probe ids corresponding to the LocusLink ids as values.

Usage

Arguments

baseName baseName a character string for the name of platform specific annotation data package
