Sun, There are hundreds using R for microarray analysis. You probably want to avail yourself of the bioconductor tools (http://www.bioconductor.org). 20,000 rows with 6 data values is a small data set, by microarray standards, and is easily handled by R and the bioconductor tools. I routinely analyze a couple of hundred experiments with 40-50k rows, and most of the time, that doesn't push R very hard (on my 2 processor, 4Gb machine, at least).
