contour for plotting confidence interval on scatter plot of bivariate normal distribution
Dear all,
I created a bivariate normal distribution:
set.seed(138813)
n<-100
x<-rnorm(n); y<-rnorm(n)
and plotted a scatterplot of it:
plot(x,y)
Now I'd like to add the 2D-standard deviation.
I found a thread regarding plotting arbitrary confidence boundaries from

kerneld and module security
Here''s a neat trick for a machine running kerneld:
not_root@machine$ /sbin/ifconfig isofs
loads ''/lib/modules/(kernel version here)/fs/isofs.o''.
/sbin/ifconfig when run as non-root queries a network interface for
its configuration. However, if the interface is unknown it also tries
to load the module that implements that interface using the name of the
interface as

y-axis with "break"
Dear R-users
I would like to draw a barplot with a special y-axis. Most of my data points are
in the range from -50 to 50, apart from one value that is 550. I would now like
to have a y-axis from -50 to 50, then a "break" and the "rest" of the y-axis,
let's say from 500 to 600. In order to make clear what I'm trying to do, I

Is it possible to have one pie chart of a large radius and then a pie

Moving from Splus to R: irregular and regular time series
Dear R developpers,
I am a user of Splus since many years and I have developped lots of
functions to plot graph of data and model results of irregular or
regular times series.
In Splus regular times series are created using the rts function and
irregular time series using the its functions. In both cases, times is
given as a numeric vector.

Re: Linux Sound driver ("OSS free") vulnerability
Synopsis
Applications can mmap sound driver DMA memory into their
address space (see http://www.4front-tech.com for API
documentation). When the application closes the audio fd,
it still has the mapping to the DMA buffer. It can now
interfere with other apps playing/recording audio.
(i.e. the driver should prevent opening the sound driver
again while another app holds mappings open to it)

How to construct confidence bands from a gls fit?
Dear R-list,
I would like to show the implications of estimating a linear trend to
time series,
which contain significant serial correlation.
I want to demonstrate this, comparing lm() and an gls() fits, using
the LakeHuron
data set, available in R.
Now in my particular case I would like to draw confidence bands on the plot and
show that there are differences. Unfortunately, I do not know how to

From S-Plus to R
Dear Isabelle,
for most of my work I have switched from S-Plus to R, because it is
easier to make scripts with due to the better documentation and some
other more reasonable implementations. And there was also a cost
issue with the S-Plus Server, which is not for free at all.
In R I use the its package for time series, which is quite sufficient
for my needs. The only problem I encountered was

Calls which cross trust boundaries
Many of the security problems we''ve had to deal with recently have
been where one program invokes another when no good level of trust
exists between them.
Currently solutions to this requirement are produced on an ad-hoc
basis, usually involving set-id programs (often setuid root),
superuser daemons calling user programs for `upcalls'', or both.

Maybe this is not the right platform to ask this, but I'm looking desperately for a test which is calculating confidence intervals from diversity measurements (non-normaly distributed) (fishers alpha diversity).

function kde2d
Good evening,
I am Marta Colombo, student at Milan's Politecnico.
Thank you very much for your kindness, this mailing list is really useful.
I am using the function kde2d for two-dimensional kernel density estimation and I'd like to know something more about this kind of density estimator. In particular I'd like to know: what bandwidth is used ?

Question on density values obtained from kde2d() from package MASS
Hello,
I am a little bit confused regarding the density values obtained from the function kde2d() from the package MASS because the are not in the intervall [0,1] as I would expect them to be. Here is an example:

Joint density kde2d works improperly?
Dear all,
Please, look at the following code:
attach(geyser)
f1 <- kde2d(duration, waiting, n = 5)
a <- 0
for (i in 1:5){
for (j in 1:5){
a <- a + f1$z[i,j]
}
}
As far as I understood from Help kde2d returns matrix elements of which are
values of joint probability mass function Pr(X=x,Y=y) therefore, sum of its
elements should sum to 1.
Which is not the case from my check.

Estimate region of highest probabilty density
Estimate region of highest probabilty density
Dear R-community
I have data consisting of x and y. To each pair (x,y) a z value (weight) is assigned. With kde2d I can estimate the densities on a regular grid and based on this make a contour plot (not considering the z-values). According to an earlier post in the list I adjusted the kde2d to kde2d.weighted (see code below) to estimate the
