R help - Feb 2011 - getBM in biomaRt

I'm using 'getBM' function in Bioconductor package 'biomaRt'
to retrieve gene ids based on known chromosome locations.

The question is getBM just only return one gene id once a time,  even a query is
mapped to multiple genes. What's the criteria for picking that special one?

Two things:

(i) This is related to bioconductor, so you should repost this
question to the bioconductor mailing list. Subscribe here:

(ii) When you repost to bioconductor, please elaborate on your
question a bit more and also include a small reproducible example that
shows the problem you are having, since I'm not sure exactly what you
mean by the way you describe your question above.
