See the axis() function.

x <- rnorm(20)
y<- rnorm(20)

You may want to also consider plot(x,y,xaxt="n",yaxt="n") to suppress the 
x and y axes which you can rebuild with axis() to fit your purpose. See 
also the help file on par() for all kinds graphicals arguments. E.g., you 
may have to reset your margins with the "mai" options if you need enough 
space to include a label on the right axis.
