R help - Nov 2007 - Plot segments with different colors

Hello Everybody,
I'm trying to plot(x,y) using different colors. 
I have to cut (x,y) into sub intervals.
And I want to plot this sub intervals using colors. But infortunally I don't
know how to do this with R.
Can any body help me please?

My code is looking like :
x<-c(tvar[1:t0],tvar[t0:(ts)],tvar[ts:n])
F<-c(var[1:t0],var[t0:(ts)],var[ts:n])
plot(x,F,xlab="Zeit [s]",ylab="Variation [%]",col =
"red",type="l")

Thanks

the 'col' argument of plot() may also be a vector, e.g.,

x <- sort(rnorm(15))
y <- rnorm(15)
plot(x, y,
    col = rep(c("red", "blue", "magenta"), c(5, 6,
4)))


I hope it helps.

Best,
Dimitris

Hi Adel,
Perhaps you would be interested in the color.scale.lines function in the 
plotrix package that allows one to color each defined segment of a line 
separately.
