hide scatter points

I need to hide scatter points and just leave the linear regression
line. ?I have tried to color the points "white", but that does not
work.

A working example, I need the green plotted points to be transparent or hidden.

x2 <- seq(1,200,.5)
y2 <- seq(5,204,.5)
plot(x2, y2, pch=16, col="green")
model<-lm(y2~x2)
abline(model, lty=3, lwd=4, col="black")

Thanks ahead of time,

keith
