You might instead look at Ensembl via the biomaRt package -- the HapMap
Biomart interface does not (yet) implement the XML Mart interface that BiomaRt
uses (boo hiss). These _are_ vectorized. I have made a couple of
wrappers specific to SNPs, which you can email me about if they sound
useful ("snps.by.name", "snps.by.region", "annotate.snps", "maf": they
probably need to be updated before I show them off ;)).
