[BioC] biomaRt proxy issues

[James W. MacDonald]

Hi Bill,

I am not sure you need to pass anything to listMarts() unless you aren't 
sure what mart to use. It seems to me that the critical function would 
be getBM() to which you can pass an already formed curl object.

Can you do something like this?

mart <- useMart("ensembl","hsapiens_gene_ensembl")
curl <- getCurlHandle()
curlSetOpt(.opts = 
list(proxy="xxx.yyy.com:8080",proxyuserpwd="myid:mypassword"),curl = curl)

getBM(c("entrezgene","uniprot_genename"), "entrezgene", 
c(1,10,100,1000), mart, curl)


Best,

Jim
