Dear all,

I am creating functions with the "three dot" strategy. I wold like to have suggestion when writing multiple functions that calls multiple functions with "...".

I will give you a couple of example:

>a=1:5
>b=6:10
>d=3:7

>example=function(x,y, z, ...){

   plot(x,y, ...)
   points(x,z, ...)

}

>example(a,b,d)

how can I set different parameters for points and plot functions? for example in plot I want to have bigger dots (lwd=3), while in the points I want to have green dots.

any suggestion?

thank you.
