plot just one page of lattice plot
Great stuff, thanks. I'm copying this solution to R-help for reference.

ts model challenge (transfer function)
Dear useRs,
I am trying to model a time series with a transfer function. I think
it can be put into the ARMA framework, and estimated with the 'arima'
function (and others have made similar comments on this list). I have
tried to do that, but the results have so far been disappointing.
Maybe I am trying to make 'arima' do something it can't...
The data are time series of

equivalent to "require" for imports? (cairoDevice)
Hi R-devel
I use the packages RGtk2 and cairoDevice. The cairoDevice package has
a few stand-alone functions, plus "asCairoDevice" which depends on
RGtk2 and calls require(RGtk2). So cairoDevice lists RGtk2 under
"Suggests" in the DESCRIPTION file. It can not Import RGtk2 because
that would force all users to install RGtk2.
The upshot of this is, if you *import* the RGtk2

plot.dendrogram xlim/ylim
list(...),
I would like to zoom in to the leaves of large trees in a dendrogram
plot. The playwith package allows zooming by passing xlim and ylim
arguments to the plot call (Hmisc does this too I think). But
currently stats:::plot.dendrogram does not accept xlim or ylim. So I
would like to enable that. In place of the existing code chunk:
xlim <- c(x1 - 1/2, x2 + 1/2)
ylim <- c(0,

new package plotAndPlayGTK
Package plotAndPlayGTK provides a graphical user interface for R
plots. Wrap it around your plot commands, like playwith(plot(mydata)).
A window pops up with a Cairo plot device and a toolbar with buttons
to interact with the plot. The default buttons allow you to add
persistent labels to data points, zoom in and out and around, save the
plot to a file, and so on. Furthermore, you can edit the

time series with quality codes
list(...),
I am working with environmental time series (eg rainfall, stream flow)
that have attached quality codes for each data point. The quality
codes have just a few factor levels, like "good", "suspect", "poor",
"imputed". I use the quality codes in plots and summaries. They are
carried through when a time series is aggregated to a longer
time-step,

navigating ggplot viewports
list(...)
I can not get at the grid viewports in a ggplot2 plot.
I know there is supposed to be a viewport called "panel_1_1" but
downViewport() can't find it. Has the viewport been popped?
I had a quick look at the functions involved (eg ggplot_plot)
but there is no obvious problem there.

interrupting R from a GUI
list(...),
I am looking for a way to interrupt R from a callback: specifically,
to interrupt plotting (typically on a cairoDevice, but would be good
if it worked with other devices too). Of course, one can interrupt R
nicely from the console with Ctrl-C (or Esc in Rgui), but I need to do
it from a GUI. Callbacks run in a new thread, so obviously stop() etc
will not work. I tried to look into how

grid.ls() after grid.remove() fails
Dr Murrell and others,
It seems grid.ls() fails after any use of grid.remove(). It gives an
infinite recursion error even in the simplest cases, and no matter
what arguments are passed to grid.ls.

bug involving quote(); ghost in the machine
Hi list(...),
I've narrowed down a weird bug. It's like a ghost in the machine, in
that functions seem to remember things that they should not be able
to. In the example below, the result of the second (and subseqent)
calls depend on what was given in the first call.
foo <- function(given = NULL) {
callObj <- quote(callFunc())
if (!is.null(given))

Replacing plot symbols w/ subject IDs in xyplot()
All,
How does one replace plot symbols with say subject IDs when using xyplot? Or
superimpose them next to plot symbols? I searched the archives under
various key words but haven't had much. Any suggestions or links much
appreciated. Sample code below.

Subsetting within xyplot()
All,
I'm having problems w/ a simple attempt to subset an xyplot.
The first plot below is a plot of y versus x for certain values of a third
categorical variable z. Now I'd like to further restrict this to certain
values of variable y. Neither of the two attempts below work. Any
suggestions much appreciated. (note: I don't want to merely use ylim since

Partial comparison in string vector
Hi list members
I have a vector of strings
x=c("w","ex","ee")
And I want to get a logical vector showing the positions where my search
string "e" matches the elements partially, i.e. is at least the left-hand
part of the target strings, i.e. I want to get a vector FALSE TRUE TRUE.
Any ideas?
Thanks

(x,y) coordinates for grid.text()
All,
When using grid.text it seems my supplied (x,y) coordinates are being
plotted only in npc (normalized parent coordinates) where (.5,.5) is the
center of the graph. How do I allow (x,y) to be coordinates corresponding
to the (x,y) values in the graph? The examples in ?grid.text seem to do
this. (I think the problem lies in how x and y are defined with respect to
unit ). Any help much
