Buggy trellis.focus() with xyplot ?
Hi:
(Tried to find a bug report about this issue, but was unable to find it, let
me know if this is a known issue)
I have been working on an interface to highlight xyplot panels on mouse
overs in JavaGD but I have stumbled with what seems to be a bug in
trellis.focus.
I am using R 2.8 with lattice 0.17-15
*** To replicate the bug:
1.- display an xyplot. For example, from the xyplot help page:

gWidgets (tcltk): problem extracting values from widgets in glayout grid
Hello,
I haven't been able to find an example for the second case below -- or
perhaps I didn't recognize it when I saw it.
Is there a value for x such that svalue(x) will return "bbb", either by
itself or as part of an array? Or do I need to do something else
entirely?
(R2.5.1; Windows XP)

Forestplot () box size question
Hi All,
I have been able to modify the x-axis to start at zero by adding xlow
and xhigh parameters; that was pretty simple. I have been unable to
find the location of the code that would turn off the information
weighting of the box size (I have smaller randomized trials getting
less weight than a much larger non-randomized trial). The function
is forestplot() from rmeta.
Thanks for any

JavaGD package
Am trying to install package JGR and, by necessity, JavaGD on a few
Linux platforms. R rev. 2.14.0. Had some success on one platform, but
am running into a problem on a new platform. I installed rJava, JavaGD,
iplots, and JGR. Things went - I thought - without a hitch. Now, when
I try to use JGR, I start R and issue the command "library(JGR)" and get

Font in JavaGD() & pdf()
Dear r-helpers,
When I do an xYplot and display the result in a JavaGD() window, the
font is sans-serif (presumably Helvetica). When I send the figure to
a pdf, I get a serif font (presumably times). How do I insure that
the font in the pdf is indeed the default sans serif?

gradient fill of a grid.polygon
Dear list,
Following a recent enquiry, I've been playing with the idea of creating a
colour gradient for a polygon, using the Grid package. The idea is to draw a
number of stripes of different colours, using the grid.clip function. Below
is my current attempt at this,
library(grid)
rotate.polygon <- function(g, angle=0){ # utility function, works fine

Getting the panel location of a xyplot matrix using a mouse click in a GDCanvas
Hi:
I would like to find out the panel of a xyplot matrix where a mouse clicked.
I know this functionality is already bundled in trellis.focus but I can't
use it because I am coding a stand alone application in Java using with
GDCanvas as a graphics device.
I tried calling trellis.focus from Java with:
re.eval("t = trellis.focus()"));
However it did not work for an embedded

few idea about dealing with "Large Roaming Profiles"
Well,
I put it here. All the experience gained in about-half-an-year-management
of Samba-PDC + numerous NT4 workstations is included. Also, I'd be glad to
hear from you what did I miss!
1) when NT4-workstations are organised into "domain", there's some
action assosiated to this: "to log into domain".

Creating a .png with just an expression() in it
Hey,
I'm trying to create an image file with the results of a regression
analysis. In TeX, the line would be something like:
$ size = 0.34 + 4.3 var_1 $
Can I create a plot window with just this line in it? I tried playing
around with plot.new() or dev.new(), but didn't really find something
that worked.
Thanks in advance,

text length in grid
Hello! I first would like to compliment the authors of grid on what has been
a wonderfully useful package for me. Now, my question: Is there any way I
can specify the size of some grid.text using grid units?
I must label the regions of a plot. The regions can be either very small or
very large, so I would like to label each by fitting its text to the size of
the region in question. Ideally, I

Using key.opts in Ecdf/labcurve (Hmisc package)
I'm presumably missing something very obvious, but how does one use the

In this example, I want the key to be big and have a blue background, but
it isn't and doesn't.

controlling panel.width and panel.height in viewports
Dear all,
I'm trying to get a series of lattice levelplots to appear in
viewports in a particular way but struggling to exert fine control
over their appearence. There are two conditions: (a) I only want the
levelplot to appear (I don't want axes, colour key, etc) in the
viewport and (b) I want the levelplot to expand to the maximum
allowable space in the viewport while observing
