Extend the length of a plot axis in R?

Question

How do you extend the axis line in R to cover the extent of your data? For example, in

my data goes to about 2100 and I would like the line for the x axis to go that far, but not make a tickmark or label at 2100. Is this even possible in R?

Here is the code used to make the above plot:

hist(x,breaks=50,xlab="...",main="",xlim=c(0,2100))

Thanks.

You need to use two axis commands; one for the axis line and another for the ticks and labels.

set.seed(2); x <- rlnorm(1000, log(130))
hist(x, breaks=seq(0, 3000, by=200), xlim=c(0,2100), xaxt="n")

axis(1, at=c(0,2100), labels=c("",""), lwd.ticks=0)
axis(1, at=seq(0 , 2000, by=200), lwd=0, lwd.ticks=1)
