I run the aafTableAnn() to get the annotation information of eocli2. 
But I got the error. I did try to get the ecoli package. but it failed. Anyone help me?
> AnnTable2 <- aafTableAnn(AllGenes,chiptype,AnnCols[2]);
Loading required package: ecoli2
Error in aaf.handler(chip = chip) : Couldn't load data package ecoli2
In addition: Warning message:
In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE,  :
  there is no package called 'ecoli2'

Apparently, the following information are helpful to fix it. 
> chiptype
[1] "ecoli2"
"AllGenes" variable includes probe ids.

I guess "ecoli2" microarry is not supported by annaffy package. or I don"t know how to download the ecoli2 package.
