[BioC] boxplot(affybatch)

[Matthew Hannah]

Hi,

Just a quick question. I just noticed that boxplot(affybatch), returns values
for n=5000. Is this correct? If so does this provide a sufficient description 
of all intensities on the chip, and how are the probesets(or probes?) selected.
Also does hist(affybatch) also use less than all of the data?

Is there a quick method to access summary stats, 5 number + mean, of the raw 
intensities?

I'm using R 2.0 and BioC devel on ATH1 affy chips (22k probesets). 

Thanks,
Matt
