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. I made some

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. (Load ellipse

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 my.function <-
