[BioC] BiomaRt query error

[Ovokeraye Achinike-Oduaran]

Hi all,

I ran a list of genes through biomaRt with the following code and it
gives me this error in the snp retrieval aspect of it. I doubt it's a
connection/proxy problem because I have that taken care of, I think
and every step prior to that seemed to have worked just fine.

Any ideas what the problem might be?

Thanks.
