[BioC] computation of average of all probes but not the actual

Hi All,

Lets say, we have a table, and want to divide the values with the row averages:

mytable <- array(1:20, dim=c(4,5))
averages <- apply(mytable, 1, mean)
result <- mytable/averages

How can I make this in a way in which each probe is divided by an average which
was calulated by all probes excluding the actual probe?

Thank you:
