R - Customizing X Axis Values in Histogram

Question

I want to change the values on the x axis in my histogram in R.

The computer currently has it set as

0, 20, 40, 60, 80, 100.

I want the x axis to go by 10 as in:

0,10,20,30,40,50,60,70,80,90,100.

I know to get rid of the current axis I have to do this

(hist(x), .... xaxt = 'n')

and then

axis(side = 1) .....

But how do I get it to show the numbers that I need it to show?

Thanks.

Solution

The answer is right there in ?axis...

dat <- sample(100, 1000, replace=TRUE)
hist(dat, xaxt='n')
axis(side=1, at=seq(0,100, 10), labels=seq(0,1000,100))

Looks like xaxt is now depricated in the call to hist()

@polyphant -- Hmm. That's odd. It still works just fine for me in R version 3.1.2 (though any explicit mention of it seems to have been removed from the documentation).

Just tried again to be sure and it now works (sorry..) but it has disappeared from the docs. You can call axes=F but this removes both axes.
