Answer 1

The code in your edit does not work properly since you didn't load gridExtra.

library(gridExtra)
y <- arrangeGrob(p1, p2, ncol = 1)
class(y)
#[1] "gtable" "grob"   "gDesc"
grid.draw(y)

Edit: since version 2.0.0, my comment about grid dependency below is no longer valid, since grid is now imported.

Edit: With gridExtra version >= 2.0.0, there is no need to attach either package,

p <- ggplot2::qplot(1,1)
x <- gridExtra::arrangeGrob(p, p)
grid::grid.draw(x)
