Hi,
Here is one option, though this may be a bit tricky for you if you are
new. ggplot2 is based on grid graphics, so using grid you can obtain
more customization. There may be easier ways and even within grid it
may be possible to do more simply than I am demonstrating, I am still
finding my footing with that package. Example code follows that
should reproduce the attached PDF.
Cheers,
Josh

require(ggplot2)
## some plots using the built in "mtcars" dataset
p1 <- ggplot(melt(as.data.frame(lapply(mtcars, scale))),
aes(x = variable, y = value)) +
geom_boxplot() +
geom_jitter()
p2 <- ggplot(melt(abs(cor(mtcars))), aes(x = X1, y = X2, fill = value)) +
geom_tile()
p3 <- ggplot(mtcars, aes(x = wt, y = disp, colour = factor(am))) +
geom_point() +
geom_smooth(method = "lm", aes(group = 1), se = FALSE)
p4 <- ggplot(mtcars, aes(x = hp, y = mpg, size = factor(cyl))) +
geom_point()
## Start a new device with a specified size
dev.new(width = 11, height = 8.5)
## use the grid package to customize the layout
pushViewport(vpList(
viewport(x = 0, y = .45, width = .5, height = .45,
just = c("left", "bottom"), name = "p1"),
viewport(x = .5, y = .45, width = .5, height = .45,
just = c("left", "bottom"), name = "p2"),
viewport(x = 0, y = 0, width = .5, height = .4,
just = c("left", "bottom"), name = "p3"),
viewport(x = .5, y = 0, width = .5, height = .45,
just = c("left", "bottom"), name = "p4"),
viewport(x = 0, y = .9, width = 1, height = .1,
just = c("left", "bottom"), name = "title")))
## Add the plots from ggplot2
upViewport()
downViewport("p1")
print(p1, newpage = FALSE)
upViewport()
downViewport("p2")
print(p2, newpage = FALSE)
upViewport()
downViewport("p3")
print(p3, newpage = FALSE)
upViewport()
downViewport("p4")
print(p4, newpage = FALSE)
## add an overall title (note I left space for it and gave it its own viewport)
upViewport()
downViewport("title")
grid.text("Four Plots created by the Excellent ggplot2 package",
x = .5, gp = gpar(fontsize = 18))
