Hi, I was trying to use par(mfrow) to put 4 heatmaps on a single page. However, I get one plot per page and not one page with 4 plots. What should I modify? Test code is given below: test = matrix(rnorm(60), 20, 3) pdf(file='test.pdf',width=10,height=8) par(mfrow=c(2,2)) heatmap(test) heatmap(test) heatmap(test) heatmap(test) dev.off() thanks!

Dear Brian If you look at ?heatmap and the second paragraph of the Note you will see that it is behaving according to its documentation.

The answer is "don't do that" because that function abuses par. Use lattice or ggplot2 with grid graphics to plot multiple heatmaps. https://stackoverflow.com/questions/15114347/to-display-two-heatmaps-in-same-pdf-side-by-side-in-r -- Sent from my phone.

Hi
If you are really wedded to heatmap(), you could also use
'gridGraphics', something like this ...
library(gridGraphics)
grid.newpage()
pushViewport(viewport(0, .5, .5, .5, just=c("left",
"bottom")))
grid.echo(function() { heatmap(test) }, newpage=FALSE)
popViewport()
pushViewport(viewport(.5, 0, .5, .5, just=c("left",
"bottom")))
grid.echo(function() { heatmap(test) }, newpage=FALSE)
popViewport()
