Xiwei Wu, I get same issue, did you solve your problem ? It seems to me that the DBI driver is not appropriate to R2.2... regards --------------------------------------------------------------------- Dear list: I just installed biomaRt1.4.0, RMySQL, and DBI. I am using R2.2.0 with BioC 1.7. I got error message when trying to connect mart: > mart <- martConnect() Error in mysqlNewConnection(drv, ...) : RS-DBI driver: (could not connect anonymous at ensembldb.ensembl.org on dbname "(null)")

Hi Michel, You are probably behind a firewall which doesn't allow MySQL queries to go through. Either ask systems to enable MySQL queries or have a local install of Ensembl mart and use biomaRt on that database. best, Steffen > > Xiwei Wu, > > I get same issue, did you solve your problem ? > It seems to me that the DBI driver is not appropriate to R2.2... > > regards > > --------------------------------------------------------------------- > Dear list: > > I just installed biomaRt1.4.0, RMySQL, and DBI.
