Hey all,
We are in the (very) early stages of experimenting with something that
seems relevant here: classed identifiers. We are using them for
database/mart queries, but the same concept could be useful for the cases
you're describing I think.
E.g.
> mysyms = GeneSymbol(c("BRAF", "BRCA1"))
> mysyms
An object of class "GeneSymbol"
[1] "BRAF" "BRCA1"
> yourSE[mysyms, ]
...
This approach has the benefit of being declarative instead of heuristic
(people won't be able to accidentally invoke it), while still giving most
of the convenience I believe you are looking for.
The object classes inherit directly from character, so should "just work"
most of the time, but as I said it's early days; lots more testing for
functionality and usefulness is needed.
