Re: [R] multiple lines on multiple plots
Going back to a previous graph does not automatically restore the coordinate
system (as you noticed). But you can store that information (lot less info
than your data in most cases) and reset it manually. Try:
x- 1:10
y- (1:100)*3
par(mfcol=c(2,1))
plot(x)
tmp1 - par('usr')
plot(y)
tmp2 - par('usr')
par(mfg=c(1,1))
par(usr=tmp1)
lines(x)
par(mfg=c(2,1))
par(usr=tmp2)
lines(y)

Subject: Re: [R] multiple lines on multiple plots
Thanks for all the replies. Yes, I agree that calculating all the data
first is a simple solution which also has the benefit of making the
axis
choice easier to get right, but on the downside it requires storing an
order of magnitude more output than my original sequential approach
would have done. Not actually a problem for me right now, but may be
for
larger cases and certainly seems inelegant in general. So I'm still
interested to know if there is some practical way of returning to an
earlier plot. I suppose I could artificially scale the data to make it
match the wrong axes. But that would be horrible.
(The example was deliberately simple, but in reality I want to loop
through a bunch of simple simulations each of which generates several
types of output, and create a graph for each type of output.)

This is much easier than trying to keep track of what the dimensions
are. Also if the data you want to add is outside the plot, then you
have issues with clipping; knowing what the dimensions of all the
data
you want to plot is a reasonable way to go.

Re: [R] multiple lines on multiple plots
Thanks! I'd seen this sort of trick mentioned in places, but didn't twig
what it did. This is exactly what I was looking for.

Hi, ggplot2 automatically adjusts its axes when new data are added to plots; however you wouldn't get an automatic legend if you constructed plots that way.
