I only have the script to interpret. Does exprs function need you to specify the subset in parathesis eg. exprs(x)?
Your function will work or not depending on your dataset : 1) If you created a matrix named
exprs
containing your numeric data then it is ok 2) If you need the functionexprs()
to get the numeric data from aeSet
object because you did not create this matrix before, then you should useexprs(your_eSet_object)
So you need to further clarify your problem here
