library(ggplot2)
data(diamonds)
randind <- sample(nrow(diamonds),1000,replace=FALSE)
dsmall <- diamonds[randind,]

a= qplot(carat, data=dsmall, geom="histogram",binwidth=1)
b= qplot(carat, data=dsmall, geom="histogram",binwidth=.1)
c=qplot(carat, data=dsmall, geom="histogram",binwidth=.01)

grid.newpage()
pushViewport(viewport(layout = grid.layout(2, 2)))

print(b, vp = vplayout(2, 1))
print(c, vp = vplayout(2, 2))
