Reads the specified file, which defines phenotypic data for a
set of .CEL files. Reads the specified files into an
AffyBatch
object and
then creates a phenoData
object, defining the
experimental factors
for those chips. This function deals with different array types by
generating a pseudo arrayset containing only the probes in common. It
does this by finding the smallest chip type in the set, and using this
as a template. Probesets that aren't shared are set to 0. Other
probesets are copied in. Note that this means that spots that were in
one place on one array, appear to be at a different place on
another. What this does to position specific background correction
algorithms (such as mas5) is left as an exercise to the
reader). Beware...
