multcomp on significant interaction in coxme model
Dear R community
I currently try to get post hoc multiple comparisons with the package
multcomp from a cox mixed-effects model, where the survival is explained
by two variables (cover with levels: nocover and cover; treatment with
levels: tx, uv, meta), whose interaction is significant.
I read Hothorn, T. 2011: Additional multcomp Examples and there is an
example involving a two-way ANOVA with

Error in solve.default
I am trying to run the following function (a hierarchical bayes linear
model) and receive the error in solve.default. The function was
originally written for an older version of SPlus. Can anyone give me some
insights into where the problem is?

Problem getting a dovecot proxy to connect to another dovecot machine via STARTTLS
Hi,
I'm having a bit of a problem trying to setup a dovecot proxy. I have a
setup with two nodes. One is a working Dovecot/Postfix mail server (node
a). The other is running a dovecot proxy and roundcube webmail.
Currently I can telnet to port 143 (or openssl s_client to port 993) to
localhost on node b. I can then login to a test account on node a. This all
works.

help: advice on the structuring of ReML models for analysing growth curves
Hi R experts,
I am interested on the effects of two dietry compunds on the growth of
chicks. Rather than extracting linear growth functions for each chick and
using these in an analysis I thought using ReML might provide a neater and
better way of doing this. (I have read the pdf vignette("MlmSoftRev") and
"Fitting linear mixed models in R" by Douglas Bates but I am not

two lmer questions - formula with related variables and output interpretation
Hello,
I have been attempting to set up a lme and have looked at numerous posts
including 'R's lmer cheat-sheet' as well as reading a number of papers and
other resources including R help, but I am still a little confused on how to
write my model (I thought I had it).
I have asked a number of questions on different forums; most of which have
been resolved.

data frame manipulation - splitting monitoring interval and assigning stage
Hello, everyone.
I'm hoping to prevent myself from doing a lot of pointing and clicking

I know the date of the first check, the date of the second check (both
currently in Julian date format), the status of the nest at the second
check (alive or failed), and the date that the nest hatched (i.e.

Updating Starcraft?
I'm having a little trouble with trying to install newer versions of
Starcraft (updates or Brood War) on a win-free Wine installation. I can
run the installer off the original Starcraft CD, and it puts all of the
files in the right place, adds a couple registry entries, and then chokes
on creating the entries in the Start Menu. Still, I can kill the process
at that point, and I have a usable

I have a question about multiple testing.
Here an example that puzzles me:

question about dll crashing R
I have ported some R code to C to make it faster.
I can perform .Call("foobar",....) once and it
works fine. Absolutely correct answer.
If I put a loop inside foobar and run the main code
routine more than 100 times, it crashes R.
Or if I call .Call("foobar"....) seperately more than
two tims it crashes R.
For the most part I am doing matirx multiplies using

Urgent - I really need some help lme4 model avg Estimates
Hello all,
If someone could take a little time to help me then I would be very
grateful.
I studied piping plovers last summer. I watched each chick within a brood
for 5 minutes and recorded behaviour, habitat use and foraging rate.
There were two Sites, the first with 4 broods and the second with 3 broods.

Use of nesting in lmer- error in numerical expression
Dear R users,
I am trying to fit a GLMM using lmer to a dataset where the brood identity
(LNRREIR) is nested within mothers identity. The reason for this is that
each mother can have several nests within each year and also between years.
I am running the following script (actually I have tried all different
combinations with LNRREIR and mother):
