[BioC] biomaRt package listMarts() error

[Steffen Durinck]

Hi Bin,

Thanks for reporting this, it is a bug the listMarts function and I will 
fix it.
The BioMarts that are currently accessible with the biomaRt package are 
ensembl, vega, snp and sequence.
If you want to connect to all or some of these you can do the following:

 > mart<-martConnect(biomarts=c("ensembl","snp","vega","sequence"))
connected to:  ensembl_mart_31
connected to:  snp_mart_31
connected to:  vega_mart_31
connected to:  sequence_mart_31

Cheers,
Steffen
