SpikeIn
is ProbeSet
containing the
$PM$ and $MM$ intensities for a gene spiked in at different
concentrations. Use pData
to see the cosntrations.
spikein95
and spikein133
are instances of
ProbeSet
with the probe-level data
for six arrays (two triplicates) from the HGU95 and HGU133 SpikeIn
experiments respectively. rma95
and rma133
contain the
data pre-processed with RMA. mas95
and mas133
contain
the data preprocssed with mas5 (expression and present/absent
calls). The calls are in objects called pacalls95
and
pacalls133
.
