[R] Polygon shaded area

[Jose Narillos de Santos]

Hi all,

I have two vectors (columns) called "efinal" and "efinal 2".

I want to plot them on the same plot and "draw" a shaded area beween the
two lines using function polygon

I have tried all but I don ´t understand the polygon area, can you help me
with examples?

plot(efinal,type="l",ylim=range(min(efinal2),
max(efinal)),ylab="",main="plot")

par(new=T)
plot(efinal2,type="l",ylim=range(min(efinal2), max(efinal)),ylab="")

The efinal are two temporal series I attach?
