[BioC] biomaRt: error using dataset from HapMap_rel27 mart

[Brad McNeney]

Hello,

I'm trying to use biomaRt to access SNP data from HapMap_rel27.

> library(biomaRt)
> hapmap<-useMart("HapMap_rel27")

gives no trouble and I can list the available datasets. When I try to
use any of the datasets I get the following:

> hapmap<-useDataset("hm27_variation_ceu",mart=hapmap)
Checking attributes ...Error in bmAttrFilt("attributes", mart) :
  biomaRt error: looks like we're connecting to incompatible version
of BioMart suite.

Can anyone suggest a work-around or error in what I'm doing? Or is it
just not possible to access HapMap_rel27  with biomaRt?

Session information included at the end of this message.

Thanks,

Brad
