Re: [R] add lines() to 1st plot in layout() after calling 2nd plot()?
Since you are using LaTeX, you might consider creating the plots all in 1 step, but use the tikzdevice, this provides LaTeX (pgf) commands to create the plot that you can then insert LaTeX commands to built up the plot bit by bit. You could also look at using the subplot function in the TeachingDemos package, start with a blank plot without margins, then use subplot in place of layout to position your graphs, the examples in the help file for subplot show how to add to the subplot after creating it. Another option is to create a function that creates each whole plot, but with an argument and some if statements that will skip certain steps, then just do a for loop calling the functions to build the plots in pieces. This means replotting from scratch each step, but save these as graphics files and it is not overly complex. Hope this helps, -- Gregory (Greg) L.

Re: [R] add lines() to 1st plot in layout() after calling 2nd plot()?
This only works if all the plots are the same size and the defaults are used
for the margins. Try it with different sized figure regions in layout, the
added lines don't match at the end.

Re: [R] add lines() to 1st plot in layout() after calling 2nd plot()?
Interesting, I hadn't tried this but it probably explains why
navigation to different regions of a layout is neither documented nor
advisable.
Yet another alternative is to use Grid graphics. In particular,
1- lattice or ggplot2 provide ways to arrange several plots in a
rectangular layout, with several options to add output to a specific
panel (but they do require quite a different approach to the creation
of plots)
2- for simple enough plots (or for brave users) you could also use
low-level grid commands, and navigate to different viewports
arbitrarily placed on a page.
3- the gridBase package provides a way to combine (with some
limitations) the power of grid layouts and the output produced with
base graphics.

Re: [R] add lines() to 1st plot in layout() after calling 2nd plot()?
After some checking, I think the documentation is at best misleading
on this particular query. Nowhere could I find mention that par(mfg)
can work with layout. Instead, I found a warning that suggests
incompatibility (since mpg is explicitly tied to mfrow in ?par and
layout is said incompatible with par(mfrow)).
Relevant bits from ?par:
mfcol, mfrow
Consider the alternatives, layout and split.screen.
mfg
A numerical vector of the form c(i, j) where i and j indicate which
figure in an array of figures is to be drawn next (if setting) or is
being drawn (if enquiring). The array must already have been set by
mfcol or mfrow.
From ?layout,
Warnings
These functions are totally incompatible with the other mechanisms for
arranging plots on a device: par(mfrow), par(mfcol) and split.screen.
See Also
par with arguments mfrow, mfcol, or mfg.
I suggest the following changes,
in ?layout, section Details: The user can navigate to a given cell
using the the mpg parameter (see ?par).
in ?par, parameter mpg: The array must already have been set by
either mfcol, mfrow, or layout.
It may be that I missed an important incompatibility in complicated
layouts, but it seems to work at least for simple ones.

Instead, I found a warning that suggests incompatibility (since mpg is explicitly tied to mfrow in ?par and layout is said incompatible with par(mfrow)). Indeed. I did look around ?par, but due to this warning thought anything relating to mfrow() and mfcol() would not work anyway.

Re: [R] add lines() to 1st plot in layout() after calling 2nd plot()?
If you look at layout's help page there appears to be a worked example of an even more complex task. The answer appears to be assingning numbers to regions and then inserting par(mar= with an appropriately constructed destination arguments prior to each added piece. -- David On Oct 3, 2009, at 3:15 PM, Marianne Promberger wrote: Dear R users, I create a graphic with two plots side by side using layout(), like this: layout(matrix(c(1,2),1)) plot(1:10,main=left plot) lines(c(3:7,7:3),col=red) plot(10:1,main=right plot) The lines() obivously get added to the left plot plot. Now, I'm trying to write a function that builds up a plot bit by bit to then include it in a LaTeX presentation with overlays. I'm using dev.copy(), and it would make my life much easier (because in fact I call all sorts of additional axis() etc after plot) if I could call the above commands in this order: layout(matrix(c(1,2),1)) plot(1:10,main=left plot) plot(10:1,main=right plot) lines(c(3:7,7:3),col=red) but of course now lines() gets added to the right plot. I Is there any way to make the lines() go to the fist plot (left plot)?
