change of variance components depending on scaling of fixed effects
Dear all,
I am trying to understand the output from a binomial lmer object and why
the scaling of a fixed effect changes the variance components.
In the model p2rec is cbind(number recruits2,number recruits 1), Pop is
populations (five level factor) and ja is year (covariate running from
1955-2004). I.e. biologically I am interested to see how the proportion

Which features would you like to see on the crantastic.org community portal?
Hi,
As some of you know, one of the R Projects ideas for GSOC 2009 is to
expand the crantastic.org portal. Some ideas for what should be done
is mentioned in Hadley Wickham's project description [1], others have
been briefly mentioned on this mailing list before. Undoubtedly,
however, there are many other good ideas out there that could be
implemented. Please suggest any ideas you might have

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.

Using MuMIn - error message
Hello,
I hope that you can bare with me. I am new to models, but I think I have a
pretty godd understanding of how to run them now, including how to use AICc
and Anova. The issue is that I have many factors that I wish to compare so
doing each one at a time would take forever.
I came across the MuMIn package and I was so excited, however I am getting
an error message and i don't know why.

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

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
in Excel. I have a dataframe of bird nest check observations, in which
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

Menu - labels
Webgen uses file paths to generate multilevel menues, bread crumbs etc. And
limits the character range in paths to a-zA-Z. As the directory names are
used verbatim as menu labels this is fairly limitting for non-english pages.
Is there a way to map directory names to configurable UTF8 strings for menu
labels?

MANOVA with random factor
Dear All
I would need to perform a MANOVA with both fixed (group, sex, group*sex) and
random (brood) effects. I wonder if this is at all possible and if R does that.
At the moment, I only know that I can run a classic MANOVA with R.
Thank you

Creating tiff with 1200 dpi
Hi all,
I am trying to create images in R suitable for journal publication. I'd
like to make an image that is 3.6" wide and 5.08" length, and 1200 dpi.
When I create a tiff file that is 800 dpi and 4x4", it works (although
doesn't look good).
But when I create a tiff that is the size and dpi I want, it doesn't
work. I get the following error:

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.

Can't run nlme with nested structure
Hello!
So, my problem is following. I have bird offspring growth data and I'd
like to model individual growth curves (aim is to study asymptotes and
inflection points) with nlme according to Pinheiro & Bates 2000: first using
nlsList to generate individual curves and then nlme to study the
parameters and fixed effects. The data is structured to two levels. I
have broods and
