Hello all,

How to draw a line in plot when I know the start point(x1,y1) and end point(x2,y2)? I need make this as additional information in the graph:

plot(wl2[[1]],wl2[[2]])

I think that is possible make this with the function abline(), is possible? I looked the function lines() too, but don't understand as make.


Thanks!
Lesandro
