Thanks for the self-contained example. heatmap internally uses layout (see
docs) to arrange the plot, and its parameters can be controlled by lwid and
lhei.
So give the following a try that makes the histogram and the key same size.
However, this does not help in putting the heatmap below, because everything
is plotted in an array arrangement, as you can see from the example. You
would have to change the code to put the Key in a third row; see the region
around "layout" in function heatmap, but it is not easy.
res=heatmap.3(x, RowSideColors=rc, ColSideColors=cc,lwid=c(1.5,1.5),
lhei=c(1.5,1.5))
