[BioC] Which package "Multiget" belongs

[nbing]

Hi,

I am trying to use affy package.

library(affy)
Data<-ReadAffy()
eset<-rma(Data)

Then I found the following message:
Error in .;ocal(object, which, ...) : couldn't find function "multiget"

And I tried to search "multiget" functions with no success. I must missed some 
packages from bioconductor. Could you tell me which package "multiget" 
belongs.

BTW, I can't install bioconductor through getBioC() due to some firewall 
settings. So what I did is dowload each packages on my local machine, then 
install packages individually locally. Do i missed anythings here? And I also 
installed every packages "Affy" depended such as Biobase, reposTools, 
tkWidgets.

Thanks.

Nan
