Dear list,

I have a question on moving color keys when side color bars are added to a heatmap.
The R code below produces the color key in the upper left corner. Notice I have added side bars to the heatmap, but how could I move the color key below the image? 

------
library(gplots) 
data(mtcars) 
x <- as.matrix(mtcars) 
rc <- rainbow(nrow(x), start=0, end=.3) 
cc <- rainbow(ncol(x), start=0, end=.3) res=heatmap.2(x, RowSideColors=rc, ColSideColors=cc)
 
Thank you very much,
