I am analyzing a 10000 by 40 microarray data and need to use simulation to assess the effect of multi-comparisons. My R program is computationally intensive. When run under R1.6.0, however, only 5-20% of CPU is used and my hard disk is moving constantly. I just downloaded the R.1.6.1 beta. The R program finally uses 98% of the CPU and the disk gets a rest. Thought you might be interested. My machine is Win 2000. Jason ====Jason G.
