[BioC] Error in BioMart and wormbase

[Vinuela, Ana]

Dear all, 

I've been experience a problem with BioMart when I tried to access
wormbase. I am getting an error when I tried to use a specific dataset
(wormbase_gene). This problem do not exist when I access any other
dataset from wormbase. Besides, few months ago a used this code without
problems.   


> library(biomaRt)
> wormbase = useMart("wormbase_current", dataset = "wormbase_gene")
Checking attributes and filters ...Error in if (xmlGetAttr(xml,
"displayType") == "list" && type != "boolean") options =
parseOptions(xml) : 
  missing value where TRUE/FALSE needed

> listDatasets(wormbase)
                dataset        description version

2         wormbase_gene               Gene        
3 wormbase_anatomy_term       Anatomy Term        
4 wormbase_expr_pattern Expression Pattern        
5      wormbase_go_term            GO Term        
6         wormbase_rnai               RNAi        
7    wormbase_phenotype          Phenotype        
8    wormbase_variation          Variation 

> wormbase = useMart("wormbase_current", dataset = "wormbase_paper")
Checking attributes and filters ... Ok



I will appreciate any help.

Ana.
