R help - Oct 2009 - plot the same types of graphics on the same R graphic device

Hi,
How to plot the same types of graphics on the same R graphic device? Suppose
that we want to plot a vector y against x (using plot for instance). How is it
possible to plot y against x for different values of these two vectors on the
same device so that the plots could be compared?

Cheers,

Carol

?lines
?points

Something like :

x <- 1:10
y1 <- rnorm(10, 4, 3)
y2 <- rnorm(5,5,2)

ymax <- max(c(y1,y2))
ymin <- min(c(y1,y2))


plot(x, y1, col='red',ylim = c(ymin,ymax))
lines(y2, col='green')

Hi Carol,

It isn't at all clear exactly what you are trying to do, but you might want
to
read the help for either points() and lines() [to put more than one data pair
on a single plot], or for par, specifically mfrow and mfcol, or for layout [to
put more than one plot on a single device window].

If none of those do it, then try again with a more detailed description of what
you are looking for.

Suppose that we want to plot a vector y against x (using plot for instance). How
is it possible to plot y against x for different values of these two vectors on
the same device so that the plots could be compared?
