Hi there I recently got some affymetrix human gene 1.0 st array. I only get out the probe level data and I wonder if there is a function that is able to average the probe level data for each gene?

I only get out the probe level data and I wonder if there is a function that is able to average the probe level data for each gene?In the WGCNA package we have a function called collapseRows that can either form say a mean or take a representative probe (probeset) for each gene. See help(collapseRows) after installing and loading WGCNA. Note though that you need to supply information about which probes represent each gene. HTH, Peter
