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.
