[BioC] biomaRt proxy issues

[Raynor, Bill]

Jim,

Yes and No, the code failed on the useMart statement, which attempts to establish a connection through the firewall.

However, a google search on "RCurl Proxy authentication" turned up a passing mention to "RCurlOptions", which led me into the RCurl docs, where it is revealed that RCurl will look at that option automatically.

So this works:

options(RCurlOptions = list(proxy="uscache.kcc.com:80",proxyuserpwd="------:-------"))
# getOption("RCurlOptions")  # just checking
getURLContent("http://www.omegahat.org")
mart <- useMart("ensembl","hsapiens_gene_ensembl")


Regards,
Bill

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
