You can try something like:
>a <- 1:5
>b <- 6:10
>d <- 3:7
>example <- function(x,y, z, ..., plot.dots, points.dots){
plot.list <- list(x=x,y=y)
plot.list <- c(plot.list,list(...), as.list(plot.dots))
do.call(plot, plot.list)
points.list <- list(x=x,y=z)
points.list <- c(points.list, list(...), as.list(points.dots) )
do.call(points, points.list)
}
>example(a,b,d, pch=0, plot.dots=list(cex=2),
points.dots=list(col='green'))
Hope this helps,
