Re: [R] heatmap aspect ratio
You can change the code of layout: layout(lmat, widths = lwid, heights = lhei, respect = TRUE) layout(lmat, widths = lwid, heights = lhei, respect = FALSE) (best to create a new function my.layout with the modified code) Jacob Michaelson wrote: Hi all, Does anyone know of a fairly easy way to stretch a heatmap vertically? I've got 42 arrays and would like to be able to see as many significant genes as possible (right now I can only get 50 genes with it still being readable). In some comparisons there are several hundred significant genes. I've fiddled with the asp argument, but that doesn't give the results I'm looking for -- only scales the images, not the dendrograms. Is there any way to make the heatmap rectangular rather than square without hacking the heatmap function itself (which is where I'm headed next)?

Jacob, I use heatmap.2 from the gplots package (part of gregmisc bundle). It is more customizable than heatmap.
