Hi, 

I am trying to use the function justMAS to normlize a bunch of Affy arrays, I loaded the library simpleaffy into R, when I type justMAS, it can not find it. 

I am not sure whether this is related to the following warning message I got:

Loading required package: genefilter
Error in loadNamespace(i, c(lib.loc, .libPaths())) : 
  there is no package called 'DBI'
Error: package 'genefilter' could not be loaded

BTW, I am using R 2.6.1, and the function mas5 functions well.

Thanks,

James
