help with writing function
I'm trying to write a function that takes a vector of length n and then
takes the first value of the vector i.e j=1 and forms a new vector of
length n (i.e replicate the first value n times). This function will
then calculate the absoulte difference of the original vector and the
new vector and store the results omitting the difference between the
value and itself. This function should

Kolmogorov-Smirnoff test
I am trying to determine whether two samples are identical or not. I'm
aware that somebody can use the Kolmogorov-Smirnoff test to compare
empirical distributions, but since my samples have ties I'm not sure if
I'm getting the right p-values for the comparison. Can the
Kolmogorov-Smirnoff test be adjusted for the case when ties exists and
are there any functions that already

kernel smoothing of disease rates at locations
I want to do kernel smoothing on the standardised mortality rates at
specified location(x-y coordinates) and be able to produce contour map.
I've tried to use the package called fields in R (function smooth.2d)
but the problem is I get negative results after smoothing and I do not
understand why? Your contributions will be highly appreciated or if
there is any package that can do this I

dovecot 1.0 to 1.1 upgrade and filesystem separators
Dear All
I have a test system where I am trying out 1.1.4
On the old 1.0rc6 (!) system I had edited:
src/lib-storage/index/maildir/mail-storage.h
to change:
#define MAILDIR_FS_SEP ';'
#define MAILDIR_FS_SEP_S ";"
so I can get some mail folder hierarchy and '.'s in
folder names - this all worked perfectly.
Under 1.1.4 the MAILDIR_FS_SEP lines are no longer present.

Splitting data
I want to implement the following algorithm in R:
I want to split my data, use a t test to compare both means of the groups to see if they significantly differ from each other. If this is a yes (p < alpha) I want to split again (into 4 groups) and do the same procedure twice, and stop otherwise (here the problem arises). As a final result I would have different groups of data.

Confidence ellipse for correlation
Hello,
SAS' point and click interface has the option of produce a scatterplot with a
superimposed confidence ellipse for the correlation coefficient. Since I
generally like R so much better, I would like to reproduce this in R. I've
been playing with the ellipse package. In order to have the points and the
ellipse on the same graph I've done the following.

indentation in Rd-help files
Dear colleagues,
Happy New Millennium, first of all!
It would be very nice to be able to use indentation inside \code{ } as
well, not only in \examples{ } when writing Rd-help files. Such a
situation arrises, for instance, if one wishes to include a small piece
of code in the _main_ text but not in the end as \examples{ } command
does. The only way I know to put the next 3 lines

manova in R
Dear R-users,
Does anybody know if analogs of the following S-plus functions are
available (or planned to be) in R:
manova - multivariate analysis of variance
faces - Chernoff faces plot
spin - 3D visualization of data
Another thing: are there functions for solving linear programming
problems in R or Splus?
Thank you in advance,

What's the latest on RC2 and Thunderbird
Hi
Just been reading a few threads on the sent-mail hang problem on
Thunderbird (TB) and dovecot 1.0RC2
I'm getting reports from WinXP SP2 users running TB 1.0.7, server
CentOS 4.2 and dovecot 1.0RC2
There were some suggestions:
* Set max cached connections to 1 in TB - but this can result in access problems
with blocking processes
* Upgrading to TB 1.5.0.5 - not guaranteed to work
*
