Hey all,
I can't for the life of me figure out what I'm missing here. I'm trying
to change the color of the line in a time series type plot. I can
change the point colors and symbols no problem, but for some reason the
colors do not get passed to the lines, regardless of if I do type="b" or
type="l". The sample code I'm using is below.
Because lines are not segments. For what you want to do,
you'll have to use the segments() function. Perhaps there's
something in the plotrix package.

Any help would be greatly appreciated.
Also, please CC me, as I only get daily summaries of the mailing list.
Thanks,

## Changing plot attributes through the plot
set.seed(33)
x<- rpois(7,lambda=7)
y<- rpois(7,lambda=5)
cols.x<- c(rep("black",2),rep("red",3),rep("black",2))
cols.y<- c(rep("blue",3),rep("yellow",2),rep("blue",2))
points.x<- c(rep("x",2),rep("O",3),rep("x",2))
points.y<- c(rep(8,3),rep(17,2),rep(8,2))
plot(x,col=cols.x,pch=points.x,type="b",ylim=c(0,15))
points(y,col=cols.y,pch=points.y,type="b")
