[PATCH] Annotate shapes, text and dbus support
Here are my patches to add extra shapes to the annotate
plugin. I have also added dbus support and made a few things
configurable.
The new tools available are Line, Rectangle and Circle, the
original is called Brush. There is no selection line at the
moment because I do not understand OpenGL yet. Hopefully
these patches can be added and something added later.
There is an extra action called

Kernel density estimate plot for 3-dimensional data
Hi!
I have a problem with Kernel density estimate plot for 3-dimensional data in ks-package.
Here the example:
# load ks, spatstat
# three-dimensional kernel density of B
B <- pp3(runif(300), runif(300), runif(300), box3(c(0,1)))
x <- unclass(B$data)$df
H <- Hpi(x)
fhat <- kde(x, H=H)
plot(fhat)
plot(fhat, axes=FALSE, box=FALSE, drawpoints=TRUE);

3-d kernel smooth by the "kde" function
Dear R community,
I'm having hard time to understand the kde function in "ks" package. Let me
use a 3-dimensional kernel smooth example to explain my question using the
elevation data in geoR.
### here is what I did ###
library(ks)
require(geoR)
data(elevation)
elev.df <- data.frame(x = elevation$coords[,"x"], y =
elevation$coords[,"y"], z = elevation$data)

plot implicit function
Dear Ying,
A simple way to obtain what you want is the following:
1) Select an x-y mesh where you want to plot the function, using
xs<-seq(xmin,xmax,length.xs)
ys<-seq(xmin,xmax,length.ys)
2) Define f as a function of (x,y) and compute the values of f over the x-y mesh, by using
zs<-outer(xs,ys,FUN=f)
3) Draw a contour plot at level 0:
contours(xs,ys,zs,levels=0,drawpoints=FALSE)

Kernel smoothing ("ks" package)
Dear R users,
I'm trying to determine local population centers in a region through kernel
smoothing. What I have is population density in each neighborhood, which
can be presented as point density. So in my data set “pop”, I have three
columns for about 1000 neighborhoods: x (x coordinate), y (y coordinate),
and z (population density at xy). I searched R documentations and found
that the
