Dear all,

I am trying to get ALL the gene names (symbol) and their corresponding locus
link ID from around 10 different Affymetrix platforms, but I am not quite
sure how to do that.....effeciently.

I know I could use the aafSymbol from the annaffy package or the getLL /
getSYMBOL from the annotate package to do that, but all of these functions
require to input a set of identifiers (the probesets), and in my case, I
will have to get ALL the probesets from my experiment first, and then call
the function to get all the Locus Link id / symbol corresponding to that
chip.

Do you guys have some more effecient ways to retrieve all the locus link id
or the symbol from different affymetrix platforms ? I greatly appreciate for
the help.

Thanks a lot,
