\title{Indicator for polymorphic probes}
  This functions uses the annotation slot of the AlleleSet object to load
  the corresponding annotation package and determine whether each probe
  in the object interrogates a polymorphic or nonpolymorphic allele. For
  instance, in the Affy 6.0 platform roughly 900,000 of the 1.8 million
  markers are for polymorphic alleles.
