Hello, Can anyone tell me how to display heatmap with gene names instead of Affy probes when displaying heatmap from Affy exprsSet. I looked at the heatmap function and exprs class but I am at a loss as how to change the name on the heatmap to Gene name instead of Affy ID. I managed to get the geneids as follows : geneid <- mget(geneNames(eset), envir = hgu133aSYMBOL) # get gene symbols but would be greatful for any advice on what to do next to get heatmap with gene names instead of Affy IDs. Many thanks Ruppert.

There is an argument to the heatmap function called labRow which can be used for this purpose. Sean
