独立于x值更改x轴标签

Question

I have a problem with the x-axis labelling.

I created a lm model(first.stage) and plotted the residuals using the code:

plot(first.stage$residuals,ylab="Deviation",xlab="Year",type="l",col="blue")

Now I'd like to change the x-axis labelling independent from the x values.

More precisely, I want to show the years 1960-2010 on the x axis. I tried a lot nothing worked.

If you want to set custom tick marks for your x axis, set xaxt = 'n' in the plot() call, then use axis(1, at = c()) to set the new tick marks. For example,

plot(mtcars$wt, mtcars$mpg, xaxt='n')
axis(1, at = c(1.5, 2.5))
