R help - May 2013 - plotting 2 time series data on the same graph

Hi all,
I have 2 time series variables : X_t and Y_t  where  t=0,1,2,.......,100
I want a plot containing the line charts( time plotted on the x-axis) for
both these variables.

Hello,

Where is the reproducible example? See

http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example


Anyway, see if this does what you need.

set.seed(1)
x <- cumsum(rnorm(100))
y <- cumsum(rnorm(100))

ylm <- range(c(x, y))
plot(as.ts(x), ylim = ylm)
lines(y, col = "blue")

# Or in one instruction
matplot(cbind(x, y), type = "l")


Hope this helps,

Rui Barradas
