[R] Setting axis scale for a boxplot

[David Arnold]

Hi,

I have this code:

par(mfrow=c(3,1))

x1=rnorm(10,60,1)
x2=rnorm(10,65,1)
x3=rnorm(10,70,1)
boxplot(x1,x2,x3,horizontal=TRUE,main="Example 1")

x1=rnorm(10,60,4)
x2=rnorm(10,65,4)
x3=rnorm(10,70,4)
boxplot(x1,x2,x3,horizontal=TRUE,main="Example 2")

x1=rnorm(10,60,9)
x2=rnorm(10,65,9)
x3=rnorm(10,70,9)
boxplot(x1,x2,x3,horizontal=TRUE,main="Example 3")

par(mfrow=c(1,1))

How can I set the horizontal axis limits on all three images to be the same
for sake of comparison?

D.
