I don't think we should change the visibility of the xy2i functions
without going through the deprecation cycle.
But in general, I like your suggestion. Teaching affy to grab the
appropriate function seems sensible. Personally, I think it is fine
to have these functions exported. You can still get the right one
when using affy::xy2indices. Symbol masking is a fact of R.
But having the dimensions accessible in the CDF package also makes
sense to me and is easy so I'm still in favor of adding hgu95av2dim.
And the xy2i and i2xy functions should use it...
