[BioC] biomaRt

[João Fadista]

Dear Steffen Durinck,

I downloaded today the biomaRt package from Bioconductor website and my R version is also the latest.
When I use biomaRt without setting my proxy it gives me this error:

> library(biomaRt)
Loading required package: XML
Loading required package: RCurl
> ensembl <- useMart("ensembl")
Error in validObject(.Object) : invalid class "Mart" object: invalid object for slot "vschema" in class "Mart": got class "NULL", should be or extend class "character"

Hi Joao,

Are you sure you need to set your proxy?
Try first to use biomaRt without setting it.

library(biomaRt)
ensembl <- useMart("ensembl")

Also make sure you use the latest available version of biomaRt (biomaRt 1.8.1 in the release version or biomaRt 1.9.8 in the devel repository.  The BioMart suite upgraded to version 0.5 this week and you'll need the latest biomaRt release to work with it.

Best regards,
Steffen

Dear all,
 
I am having some trouble using the biomaRt useMart function. I do not know what seems to be the problem. Here is what I got:
 
 
> Sys.putenv("http\_proxy" = "http://my.proxy.org:9999") ensembl <- 
> useMart("ensembl")
Error in curlPerform(curl = curl, .opts = opts) : 
        Could not resolve proxy: my.proxy.org; Host not found
