how to align axis in R so that two axes intersects

For example, I have the following simple command:

x<-rnorm(2000, 0, 30)
hist(x)

But the graph shows a gap between the line y=0 and the x-axis. I want it to be shown in the normal format, where the two axes touch on each other at a particular point (x0, y0) which I can specify arbitrarily. What is the option in R to do that?

Thank you.

I think the easiest way to do this is simply to draw it using box, since plot.histogram skips much of the plotting setup that would allow you to pass the appropriate par settings directly:

x<-rnorm(2000, 0, 30)
hist(x)
box(bty = "l")

See the section in par on bty for the possible options.

One way is to plot the x-axis separately and use line to align it with the 0 coordinate.

loc <- hist(x, xaxt="n",bty="l")
axis(1, at=loc$breaks,line=-.75)

You can specify xlim and ylim in hist.

Check

?hist

AND 

hist(x, xlim = c(-100, 100), ylim = c(0, 500))
