Hi,

I'm trying to use DO in stead of GO with some bioconductor functions. I've
made a hu6800DO bimap that associates the chip IDs with DO IDs. Now I'm
adapting existing code that calls lookUp(id, annotation, extension) and
using annotation "hu6800" and extension "DO". This is failing with:

Error in mget(x, envir = getAnnMap(what, chip = data, load = load),
ifnotfound = NA) :
  error in evaluating the argument 'envir' in selecting a method for
function 'mget'
> traceback()
3: mget(x, envir = getAnnMap(what, chip = data, load = load), ifnotfound =
NA)
2: lookUp(id, annotation, extension) at gtDO.R#144

So it looks like getAnnMap is not happy. I've looked at the source for
getAnnMap and have to own up to being mystified by it.

I think the closest 'drop-in' replacement I can find in DO for lookUp is the
Term() function, but I may be confused about what these two different
functions do.

Thanks,

Matthew
