...fixed effect instead, I got
(apparently) sensible results.
* The plot of the data (see attached, I hope the attachment gets
through) makes it clear that you have some potential balance problems.
In section/segment combinations (C-D) x (3-5) you have only a few (often
only one) observation in the (beetle.ev=1) case. Mild lack of balance is
no problem in mixed models, but such severe lack of balance can be.
(Note this doesn't guarantee a problem, but it is one of the factors
that makes estimation less stable.)

pairing data using combn with criteria
Dear All,
I have a dataframe made up of individual beetles consisting of individual
number, family number, mother's family number, father's family number, and
sex of the beetle. I would like to pair up the individuals for breeding. I
would, however, like to avoid breeding beetles of the same sex (obviously),
the same family, and with the same mo...

mixed ordinal logistic regression
Dear Colleagues,
I hope to know how ordinal logistic regression with a mixed model is made
in R. We (My colleague and I) are studying the behavior of a beetle. The
attraction of beetles to a stimulus are recorded: the response is Slow,
Mid, or Fast. They are based on the time after the presentation of the
stimulus to the beetles. Because we do not observe the behavior
continuously but do record the number of beetles near the stimulus at the
pre-det...

Quasi-poisson glm and calculating a qAIC and qAICc...trying to modilfy Bolker et al. 2009 function to work for a glm model

that I am subscribe to the mailing list I hope that this goes out:
I've been a viewer of this forum for a while and it has helped out a lot,
but this is my first time posting something.
I am running glm models for richness and abundances. For example, my beetle

Time To Pick the Mongrel BUGS Mascot!
Bradley Taylor shot me this *goldmine* of ugly ugly ugly dogs:
http://www.sonoma-marinfair.org/uglydogvote.shtml
I *have* to use one of these for the Mongrel BUGS Mascot. He''ll go on
our bug list page and replace the little beetles on the left.
Pick the dog you think best represents a lovable but defective pooch and
reply to this with your +1.
Let the voting begin!

Doubts about mixed effect models
Hi everyone!
I have some doubts about mixed effect models and I hope someone could help
me. I´m trying to analyze a dataset coming from samples of dung beetles in
the same forest fragments along 3 consecutive years (1994, 1995 and 1996)
and 14 years after (2010). I sampled dung beetles in 18 different fragments
with different sizes and different degrees of isolation. My aim is to
determine whether total species richness change over time in forest

ANCOVA when you don't know factor levels
Hello people
I am doing some thinking about how to analyse data on dimorphic animals
- where different individuals of the same species have rather different
morphology. An example of this is that some male beetles have large
horns and small wings, and rely on beating the other guys up to get
access to mates, whereas others have smaller horns and larger wings,
and rely on mobility to find mates before the guys with the big horns
turn up and beat them up. Normally what we do to see if this is
happen...

Plotting pdf of function
...rched the forum for plotting pdf's of functions but couldn't find one
that explained my question.
I have been asked to plot the pdf fX(x) = 1/pi(1+x^2). -infinity < x <
infinity.
I would be greatfull if someone might point me to a webpage that might give
me a hand.
Kindest regards

graphics in cocorresp package
I'm using cocorresp package with predictive co-correspondence analysis model.
i would need to visulize inside the graphic (plot function) the sample site numbers (is it possible to consider this a "label"?).
is there any function to do this?

Model II regression
Hello,
I am using function lmodel2 to calculate RMA regression between
life-history traits in ladybirds beetles. It works well but I am not able
to plot an RMA regression line on the scatterplot of my data. I am of
course unable to plot the confidence intervals. For ordinary least square
regression abline(lm(x~y))works well but for RMA regression,
abline(lmodel2(x~y))does not do it.

When encoded with oggenc -b 128, there is a sort of stereo separation
in the drums, while in the original they are 'solidly' positioned in the
stereo field. This also occurs with -b 160 and is barely audible with
-b 192.
ftp://slumber.dhs.org/tmp/beetles.wav.bz2
In this one there is a breathy vocal that becomes noisy and has the same
stereo effect as above. This is audible with -b 128 through -b 256.
In each of these, the part of the sound in which the artifact is audible
is a panned mono sound mixed with stereo sounds, and I can't hear it...

(including a placebo) and different experiments use different comparisons.

Concatening two maps/shapefiles...
Dear All,
I'm new with mapping and using shapefiles in R.
I use the version: R 3.2.1 GUI 1.66 with Snow Leopard Mac OS (6956)
I want to build a map of the countries of Africa, in order to add points of collecting species of beetles, for later publishing.
library(maptools)
library(mapdata)
When I put the extreme coordinates of Africa, the map began only at longitude 0? and thus lacks the west africa part:
x<-map('world2Hires', xlim=c(-18,52), ylim=c(-35,38))
I attempted with the following script:

"New" problem with polr (or optim, or ...)
...about 18 months ago (the
reviewers of the paper want something adding to it). I'm using R1.5.0,
but I couldn't see anything in the list of changes between this and
1.5.1 to suggest it would act any differently.
The data is observational, on the changes in the population status of
carabid beetles, and various attributes of the species which may or may
not explain what's happening. The response is ordinal - there are
several categories, from (roughly) "Gone Extinct" to "Suddenly all over
the damn place", and because the beetles haven't read Cochran and Cox,
