Hi all,
I'm trying to do a paired 3control vs. 2experimental chip analysis with SAM,
and my class label is :
sam.cl <- c(-3, -2, -1, 1, 2)
but this throws an error :
Error in adjust.for.mt(data, cl, var.equal = var.equal) :
Negative values are only allowed for the paired analysis. Or,
if a paired analysis should be done: There is something wrong with the class
labels.
So what should I do? Is it best to just drop one of the control chips so
that I have an equal number of control and experimental chips??? (It was
planned as a 3x3 comparison, but our core botched one of my experiemental
chips).
Thanks,
Ken
