Generating a new matrix using rbinom and a matrix ofprobabilities.
probMatrix <- matrix(runif(5*5), 5, 5) ## sets up the probs
binoMatrix <- rbinom(length(probMatrix), 1, probMatrix) ## simulates
dim(binoMatrix) <- dim(probMatrix) ## makes it a matrix also
What doesn't work?

(180000 data points)
In each case, the probeID is unique. The output I am looking for is something like this:
Gene No.ofprobes Mean_expression
A 3 0.25
Is there an easy way to do this using "cast" or "melt"? Ideally, I would also like to see the unique probes corresponding to each gene in the wide format.
Thanks in advance
