[BioC] annotation package: get probenames from gene names

[Georg Otto]

Hi,

I need some help with the annotation package:

To get the gene name for a given probe I perform something like this:

> zebrafishGENENAME$"Dr.19073.2.S1_a_at"
[1] "annexin A11a"

My question is: How can I do it the other way around, i.e. get all
probes with gene names containing "annexin"?

Any hint will be highly appreciated.

Cheers,

Georg
