R help - Sep 2009 - Creating mixed line and point graphs with xyplot

Hi

Well, I think the title says it all!? I've looked through the documentation
but I can't find a way of doing this.? The situation is that I have 4
series, say a, b, c and d.? Series a and c are plotted on the lh y axis, series
b and d are plotted on the rh (secondary) y axis.? I've worked out how to do
this.

However, I need to plot series a and b a points (symbols only, no line), whislt
c and d need plotting as lines (with no symbols).? What is the easiest way to do
this in xyplot?? Or should?I be using something else?

Thanks!

Paul

Here is an example:

make.groups() is your friend.

Cheers,
Dylan

If you represent your series as zoo series then you can do this:

library(zoo)
z <- zoo(cbind(a = 1:3, b = 4:6, c = 3:1, d = 6:4))
xyplot(z, screen = 1, type = c("p", "p", "l",
"l"))

See the three vignettes that come with zoo and also see ?xyplot.zoo
If you omit screen = 1 then the 4 will be on separate graphs.

It's hard to be specific without a concrete example, but something
like the following may work:

xyplot(..., type = c("p", "p", "l",
"l"), distribute.type = TRUE)

-Deepayan

I would use the base plot routine

plot(x,c, type='l', ylim=range(a,c))
points(x,a)
park(new=TRUE)
plot(x,d,type='l', ylim=range(b,d), axes=FALSE,ylab='',
xlab='')
pints(x,b)
axis(4)
