Hi, Is there a way to create a treemap with more than 1 grouping. I've seen a lot of examples like this: http://flowingdata.com/2010/02/11/an-easy-way-to-make-a-treemap/ but what if some of my categories have sub-categories. Is there an existing function that can handle this thanks -- View this message in context: http://n4.nabble.com/treemap-grouping-tp1570721p1570721.html Sent from the R help mailing list archive at Nabble.com.
