GHK simulator
Dear R-community,
not to re-invent the wheel I wonder if someone of you
has ever written a function to compute the GHK smooth recursive
simulator to estimate multivariate normal probabilities. See for instance

The following function delivers all permutations of 1:n.
all.perm <- function(n) {
p <- matrix(1, ncol = 1)
for (i in 2:n) {
p <- pp <- cbind(p, i)
v <- c(1:i, 1:(i - 1))
for (j in 2:i) {

Bug in boxplot.stats?
Is this a bug?
>"xx" <- c(50, 79, 120, 78, 90, 100, 78, 80,
+ 90, 80, 60, 39, 90, 85, 140, 100, 80, 80)
> boxplot.stats(xx)$stats
[1] 60 78 80 90 100
> boxplot.stats(0.1*xx)$stats
[1] 7.8 7.8 8.0 9.0 10.0
I suppose the way the numbers in 0.1*xx are internally stored may
cause this problem:

Conflict between NT-PDC and Samba 2.0.6
I've got a Solaris 2.6 SPARC system running Samba 2.0.6 and an NT-4.0sp5
PDC system. If Samba is running on the Sun system when the NT PDC is
rebooted it (the NT system) complains that there is already another PDC in
the domain. This should not be as far as I can see as I've tried
specifically to configure the Samba systems not to do this and in fact

AW: anova-bug in R-version 1.0.0? (PR#470)
I think I've discovered what went wrong.
My workspace included a function wilcox.test formerly copied from
ctest. Now ctest ist part of the distribution and because of that I
always got the message:

Error in autoload("wilcox.test", "ctest") :

I didn't take care of this message. Now I removed

density(x)
Dear experts,
when trying to estimate an kernel density function with density(x) I get the following
error message with imported data from either EXCEL or text files:
Error in density(spr) : argument must be numeric.
Other procedues such as truehist work. If I generate data within R density works fine.
Does anybody have an idea?

How is the overhead different whether your code checks it or Xapian does?

Synonyms of Abbreviations
Hello,
I am looking for a documentation or an example to use the synonym function.
I tried this
db.add_synonym("omega","xapain");
and this works by adding the flag FLAG_AUTO_SYNONYMS.
If i try to use the
db.add_synonym("omega","xapain is search engine ");
it fails why? Can xapian use synonym for Abbreviations like MBA => Master

Sticky results
Hi there,
I have a xapian index whose results are being sorted by a value, with (PHP bindings):
$enquire->set_sort_by_value($sort_data_value);
This is because I want the results returned in chronological order of publication date. However, I now have a need to have certain results be 'sticky' at the top of the resultset, regardless of their publication date. Obviously there are

patch: list shared namespace
Hi,
I've been working on a patch for dovecot 1.2 from the Kolab branch
(http://hg.intevation.org/kolab/dovecot-1.2_kolab-branch/) that
implements listing of shared namespaces. I've got something that works
in some basic way but is still missing some pieces. See the attached
patch, which also contains some installation and configuration notes.

Logit and Probit for Panel data
Dear R users/experts,
I've heard it's possible to estimate the above kinds of models in R. However, after (an admittedly brief) survey of the packages, I haven't found an obvious candidate. Can you offer any help? (Yes I'm a newby.)
