Dear List! I'm using R2.8.1 with windows. In my Analysis I use the heatmap.2 function. That works quite well except there is one little detail I can't change. I like to make the key a bit smaller than default. So I pass in "keysize=1" into the function. The key is smaller, but the main and the x y label of the key do not become smaller. So not everything is printed or it looks strange with a small key and huge letters next to it. I thoroughly studied ?heatmap.2 and ?par, but I could not find anything helpful. Any ideas to solve that? Thanks Christoph
