```Using ggplot2:

library(ggplot2)
test_data<-rnorm(100)
a=data.frame(obs=test_data,condition='None')
p1=qplot(
data=a
,x=obs
,geom='histogram'
)+coord_flip()
p2=qplot(
data=a
,y=obs
,x=condition
,geom='boxplot'
)+opts(
axis.text.y=theme_blank()
,axis.title.y=theme_blank()
)+coord_flip()
p3=qplot(
sample=test_data
,stat='qq'
,distribution=qnorm
)+coord_flip()

print(p1,vp=viewport(width=1,height=1/3,x=.5,y=1/3*.5))
print(p2,vp=viewport(width=1,height=1/3,x=.5,y=1/3+1/3*.5))
print(p3,vp=viewport(width=1,height=1/3,x=.5,y=2/3+1/3*.5))
