[R] Splitting device for ggplots?

[baptiste auguie]

Hi,

I believe you can apply the same procedure as described in Paul  
Murrell's "R graphics" book for arranging lattice plots.


library(grid)
library(ggplot2)
?grid.layout

df <- data.frame(x=rnorm(100), y=rnorm(100))
df2 <- data.frame(x <- rnorm(100), y=runif(x))

p <- qplot(x,y, data=df)
p2 <- qplot(x,y, data=df2)

pushViewport(viewport(x=0.25, width = 0.5, height = 0.8, angle = 0,
name = "leftvp"))
grid.rect(gp = gpar(col = rgb(43/255, 140/255, 190/255)))
print(p, newpage=F)
upViewport()
pushViewport(viewport(x=0.75, width = 0.5, height = 0.8, angle = 0,
name = "rightvp"))
grid.rect(gp = gpar(col = rgb(43/255, 140/255, 190/255)))
print(p2, newpage=F)
upViewport()


Hope this helps,

baptiste
