Why warnings using lmer-model with family=binomial
...y, and what I can do about that
I sometimes, but not always, get warning-messages like
nlminb returned message singular convergence (7)
in: LMEopt(x = mer, value = cv)
or
IRLS iterations for PQL did not converge
when trying to fit a model looking like this:
lmer<-(cbind(Diseased,Healthy)~Fungus+(1|Family)+(1|Fungus:Family),
family="binomial") to four similar data sets?
All four data sets consists of four columns;
Fungus (1 or 2), Family (1-30), Diseased and Healthy.

Problems with character spacing in windows metafiles...
This problem was posted a couple years ago here:
http://tolstoy.newcastle.edu.au/R/help/04/01/0231.html
Using Windows XP with R 2.3.1, I am now experiencing the same problem again:
when a plot is saved and/or copied as a WMF, the labels do not have the
correct character spacing. I am trying to insert the WMF into a MS Word
2003 document (my first mistake, I know), but even when the WMF is

seeking robust test for equality of variances w/ observation weights
Hello R community,
I am looking for a robust test for equality of variances that can take
observation weights.
I realize I can do the F-test with weighted variances, but I've read that
this test is not very robust.
So I thought about maybe adding a "weights" argument to John Fox's code for
the Levene Test (in the "car" library, "levene.test"),

How to calculate the AUC in R
Hello R-listers,
I'm working in an experiment that try to determine the degree of
infection of different clones of a fungus and, one of the measures we
use to determine these degree is the counting of antibodies in the
plasma at different dilutions, in this experiment the maximum number of
dilutions was eleven. I already checked for differences on the maximum
concentration of the antibodies in function of each clone...

Custom nonlinear self starting function w/ 2 covariates
Hello,
I'm trying to adjust a non linear model in which the biological response
variable (ratio of germinated fungus spores) is dependent on 2 covariates
(temperature and time). The response to temperature is modeled by a kind of
beta function with 2 parameters (optimal and maximum temperatures) and the
time function is a 2-parameter Weibull. Adjustments with nls or gnls work,
but I need to do mixed-effects model...

"Quality" vs. "bitrate"
I just had another thought on this topic.
What if we have a setting to select the maximum possible
bitrate instead of a target bitrate setting.
This satisfies the streaming people, but means that for
an ordinary user to set a bitrate he'll have to set the
quality to 9.999999 *and* the maximum bitrate to whatever
he wants.
ie. If he sets quality to "near CD" and max_bitrate to

Probit analysis
Respected Sir/Madam,
I have a question regarding calculation of LD50 (Lethal Dose) and IC50 (50%
inhibitory concentration) of an antimicrobial experiment.
I have used a compound isolated from a plant and observed its effect on the
fungus *Fusarium oxysporum* by the food poisoning method. Solutions of the
compound at concentrations of 0, 50, 100, 150, 200 and 250µg/ ml were added
to sterilized medium in Petri dish (9cm dia.) and after transferring the
mycelia of fungal strains, the dishes were incubated in the dark. When the

ov_pcm_seek() is very slow...
I realise the it's hard to do a seek in a variable bitrate
file but I didn't think it was this bad. It seems to vary
a lot with the file but the total time to do an ov_open()
and ov_pcm_seek() can add upp to a second or more. By this
time my DirectX buffers have wrapped around and are looping.
Can anybody think of a solution for this? I really need a
faster response time for my in-game

How to create polygons representing sampled forest plots, and how to compute D1 matrix between these polygons ?
...over the 10
ha. In each plot of 25 x 25 m I got 5 soil samples on which I will measure
a battery of variables (the explanatory variables).
What I want to study is the bêta-diversity of the ectomycorrhizal
community, so that in each plot I got about 15 pieces of root containing
some ectomycorrhizal fungus on it (response variables).
My purpose is to explain the spatial variation of the ectomycorrhizal
diversity thanks to the soil variables I will have measured.
To do so, I want to use a PCNM (or MEM).
My problem is that :
All the 24 plots are considered as points since I only give the central

Lossless/lossy hybrid?
Monkey's Audio lossless compressor (currently win32 only, free but not
open-source except decoder) author is thinking to implement a kind of
audiophile-quality lossy compression which would filter "noise bits" that
are hard to encode lossless but which are (or should be) inaudible and thus
improve lossless compression (avg. 300-450kbps). I think that implementing
something like this
