R help - May 2007 - draw two plots on a single panel

Hi,

I have 2 dataset,

plot(data1)
plot(data2),

but it comes as two graphs, can I draw both on a single panel so I can
compare them?

Thanks
Pat

See ?points and ?lines for a simple solution. Eg:

plot(data1)
points(data2)

if mean this by 'panel'.

Hi Pat,
Certainly you can
But you need to provide more details, will advise closely
In general, first you plot the ?frame? without plotting like this


plot(range(data1$x1,data2$x2), range(data1$y1,data2$y2), type=?n?) # means
just plotting a frame with xaxis ranges from x1-x2 and y from y1-y2, but no
plotting

then depends on your data type (i.e. line or scatter or blah blah) then you
have specific command for them
Give you here an example for reference:

# Two scatter plots in the same graph:

data1 <- data.frame(x1=rnorm(100,70,7), y1=rnorm(100,35,5))
data2 <- data.frame(x2=rnorm(100,78,8),  y2=rnorm(100,40,5))
plot(range(data1$x1,data2$x2), range(data1$y1,data2$y2), type=?n?) 
points(data1$x1,data1$y1,pch=17, col=?blue?)
points(data2$x2,data2$y2,pch=16, col=?red?)


Cheers
Nguyen
