SpikeIn is ProbeSet containing the $PM$ and $MM$ intensities for a gene spiked in at different concentrations. Use pData to see the cosntrations.

Source

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.
