[BioC] Mapping CDF from different array platforms

[Rifat Hamoudi]

Hello,
		Has anyone managed to compare data from different array platforms using R.
If so what is the best way to do it. In particular I am doing the comparison
of u95av2 with u133a. I am trying to do this by remapping the clones and
creating new CDF using altcdfenvs package, but does anyone know of an easier
way? I tried to use the Affy best match files ..etc but not sure if that is
the perfect way to do it.

Thanks

Rifat
