truly object oriented programming in R
Good morning! I recently implemented a KD tree in JAVA for faster
kernel density estimation (part of the code follows). It went well. To
hook it with R, however, has proved more difficult. My question is: is
it possible to implement the algorithm in R? My impression seems to
indicate no as the code requires a complete class-object framework that
R does not support. But is there an R package or

error with bbox for k12hat (splancs) bivarite k-function
Hello,
I am trying to conduct a bi-variate ripley's k using the k12hat function in
the splancs package (found here
http://rss.acs.unt.edu/Rdoc/library/splancs/html/k12hat.html). Although, I
receive an error when getting to the bboxx part of the code:
poly <- list(x=c(fire4$X, nar4$X), y=c(fire4$Y, nar4$Y))

How to scale arrows to approximately fill a plot region?
In a variety of graphic applications, I plot some data, together with
arrows representing variables
or linear transformations of variables as vectors in the same space, as
in a biplot.
In my applications, the scale of the arrows is arbitrary -- all that
matters is relative length.
I'd like to blow them up or shrink them to fit the available space in
the plot.
The origin is typically at

Place a graphic into an R-plot
I have a graphic image in a file (say a *.jpeg or *.png file) and want to
put it into a plot. I have segmented the plot area by means of the layout
function and successfully plotted my data in the appropriate segments. I
cannot find how to put my graphic image onto the same plot. Searching the
archives has shed little light on my challenge.
Many thanks in anticipation.

trellis margin sizes in absolute units
Dear R users,
I have a lot of experience with traditional R graphics, but I decided to turn to trellis as
it was recommended for spatial graphs by the sp package. In traditional R graphics
I always first set the size of the device region absolute units (e.g. mm) and then I
firmly fix the inner margins with mai and the outer margins with oma also in absolute units.
What is left from the device

ggmap crash
Not sure if this is the right place to report this, but:
Am using ggmap to generate a map of a bounding box from 161
latitude/longitude pairs and the code crashes R (in ess). Data is at
http://analysis.d8u.us/~hdiwan/plotSource.csv and the code to read it
is below. I'm not sure if ess, emacs, ggmap, R, or my laptop is to
blame. Here's the code:

italic (PR#7932)
Full_Name: G. Grothendieck
Version: R version 2.1.0, 2005-05-14
OS: Windows XP
Submission from: (NULL) (216.59.254.207)
This code:
> plot(1:10)
> text(5,5,lab=expression(italic(22*"33")))
has the effect of italicizing 33 (which is a character string) but not 22
(which is not). I would have thought that both, not just 33, would be
italicized.

Defining origin for rotation in RGL device
Hi all,
How can I tell RGL to set the center for the rotation to the origin of the coordinate system (0,0,0).
It seems that the default is to use the center of the display not the origin of the coordinate system.
open3d()
lines3d(c(0, 1), c(0,0), c(0,0))
lines3d(c(0,0), c(0, 1), c(0,0))
lines3d(c(0,0), c(0,0), c(0, 1))
TIA

S4 method dispatch and namespaces: why is default method selected

pattern on bars?
Colors are real nice, but the publication I'm preparing these barplots for
permits only black and white. The Splus plot options ``dbangle'' (or plain
``angle'') and ``density'' (as on p. 65 of MASS 1st ed.) don't seem to be
available in R. Is there another way to do this?
I'm running R 1.1.0 on Linux (intel). Thanks.
