Change Axis Label - R scatterplot

问题:

I am using the CAR library scatterplot function trying to do something similar to R: Replace X-axis with own values. However the result is badly formatted. Does anyone know how to replace the x axis values when using scatterplot? My code is below

library(car)
dat = data.frame(x=1:10, y=1:10)
scatterplot(y~x, data=dat, xlab="X axis", ylab="Y Axis", xaxt="n")
axis(1, at=seq(1,10,2), labels=letters[1:5])

With the resulting image

Reading the car:::scatterplot help page, as it seems is my calling in life, ....

reset.par   if TRUE then plotting parameters are reset to their previous values when scatterplot 
            exits; if FALSE then the mar and mfcol parameters are altered for the current 
            plotting device. Set to FALSE if you want to add graphical elements (such as lines) 
            to the plot.

Set it to FALSE and try again.

png(); scatterplot(y~x, data=dat, xlab="X axis", ylab="Y Axis", xaxt="n", reset.par=FALSE)
 axis(1, at=seq(1,10,2), labels=letters\[1:5\])
dev.off()
