Hi,
You can draw arrangeGrob in a rotated viewport,
library(gridExtra)
library(ggplot2)
ps = replicate(4, qplot(rnorm(10), rnorm(10)), simplify=F)
g = gTree(children=gList(do.call(arrangeGrob, ps)), vp=viewport(angle=90))
grid.draw(g)
though you get some warnings about clipping for some reason.
Perhaps more cleanly, you can define a print.arrange method,
(shamelessly borrowed from ggplot2),
print.arrange = function (x, newpage = is.null(vp), vp = NULL, ...)
{
if (newpage)
grid.newpage()
if (is.null(vp)) {
grid.draw(x)
}
else {
if (is.character(vp))
seekViewport(vp)
else pushViewport(vp)
grid.draw(x)
upViewport()
}
}
print(do.call(arrangeGrob, ps), vp=viewport(angle=90))
HTH,
baptiste
