I am having problem with connection to Biomart due to proxy

At first I tried to analysis get the Mart using the following command which led to error

hsapiens = useMart("ensembl",
+                    dataset="hsapiens_gene_ensembl")
Request to BioMart web service failed.
The BioMart web service you're accessing may be down.
Check the following URL and see if this website is available:
http://www.ensembl.org:80/biomart/martservice?type=registry&requestid=biomaRt
Error in if (!grepl(x = registry, pattern = "^\n*<MartRegistry>")) { : 
  argument is of length zero

Then I tried to set the proxy and I got this error

options(RCurlOptions = list(proxy="http://proxy.swmed.edu:3328", proxyuserpwd="user:pwd"))
> hsapiens = useMart("ensembl",
+                    dataset="hsapiens_gene_ensembl")
Error in listMarts(host = host, path = path, port = port, includeHosts = TRUE,  : 
  Unexpected format to the list of available marts.
Please check the following URL manually, and try ?listMarts for advice.

What do you see if you follow the instructions in those error messages and go to http://www.ensembl.org:80/biomart/martservice?type=registry&requestid=biomaRt in a browser?

Ok, so that's exactly what you're supposed to see, so at least your browser can connect to Ensembl BioMart fine. If your web browser is also using a proxy, I suggest you copy the setting being used there.
