[BioC] missing MAP locations for hgu133plus2 annotation

[Srikanth]

Hello,

I am looking at the bioconductor annotation package for hgu133plus2. I 
noticed that about 28 % of probesets do not have a MAP location listed 
for them. Could someone please point me to an updated or a developmental 
package that has missing MAP information. I called Affymetrix and they 
pointed me to their annotation csv file that has missing locations for 
29 % of the probesets.

Thank you for your help.
