[Bioc-devel] adding phenodata to heatmaps
Hello Fran?ois, I am the maintianer of the gplots package which contains the the heatmap.2 function. I would be glad to include appropriate changes to make it easier to add additional information to the plot. Please send me a copy of the modified code and manual page. -Greg

Hi everyone, I was curious about what people thought of the issue of adding phenodata (or other graphical components) under a heatmap. Heatmap.2 allows for a single row of colors, and the Heatplus package allows for several covariates, including plotting continuous values. I ended up spending a couple of hours modifying heatmap.2 to do what I wanted (before Seth pointed out to me that Heatplus existed). Would it be worth it to make that functionality more visible (maybe putting into heatmap/heatmap.2 or a function in ExpressionSet)? At this point, adding any graphical component to a heatmap requires understanding the whole layout code of the function which is not trivial. I think it would be a good idea to increase its visibility and accessibility, because it makes for much more readable figures for people dealing with complex phenoData. Heatplus has the basic functionality, but it does require some fiddling around to get 0/1 values for the phenoData (and they make some changes to where the sample and gene names are placed). I'd be happy to help a bit to get the functionality in if people think it would be worth it. Francois
