[R] Changing default plot behaviour

Use a custom plotting function, e.g.
myplot <- function(..., sidesforlabels)
{
   #sidesforlabels should be a numeric vector containing the sides that 
you want labels on
   plot(..., axes=FALSE)
   par(tcl=0.5)
   for(i in 1:4)
   {
      axis(i, labels=i %in% sidesforlabels)
   }
   box()
}

myplot(1:10, sidesforlabels=1:2)
