#Data set of Chiaretti et al
library(Biobase); library(multtest); library(genefilter)
data(ALL) #Load the data set
ALL #print an overview of the "object"
ALL@phenoData@varMetadata #Print contents of a "slot" of an object
library(genefilter) #filtering genes
X <- exprs(ALL) #expression of data matrix
So the question was " At which row are the data for the gene '32562_at'?" I can't get grep() to work I think because 32562_at is not a value, but a label. So I'm not sure what other commands can give me the answer.
The correct answer is: row 2585
