[BioC] Intensity distribution of "significant genes"

[Phguardiol at aol.com]

but with affy the problem is that genes dont have locations. each of the 
11-20 probes have a location. would you like to see the location of the 
probes for each gene? the function plotLocations can be used for this.

Yes, can we see the entire set of probes from all the genes/probesets 
differentially expressed, identified in a comparison test ? Is plot Locations going 
to tell us if there is a non random distribution of some of these ? This last 
question is also true for 2 color arrays. Is there any "spatial" tests already 
available for this kind of assessment ?
