Hi Lisa,
This query works for me, maybe the BioMart server was temporarily down
at
the time you tried the query:
>
getBM(attributes=c("affy_hg_u95av2","hgnc_symbol"),filters="affy_hg_u9
5av2",values=c("1939_at"),
mart=human.ensembl,verbose=TRUE)
<query virtualschemaname="default" uniquerows="1" count="0" datasetconfigversion="0.6" requestid="biomaRt"> <dataset name="hsapiens_gene_ensembl"><attribute name="affy_hg_u95av2"/><attribute name="hgnc_symbol"/><filter name="affy_hg_u95av2" value="1939_at"/></dataset></query>
affy_hg_u95av2 hgnc_symbol
1 1939_at TP53
Cheers,
Steffen
