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.

replace question mark with a dash
Hi:
I have the following dataset in R( thanks Gabor for your help) but now
the problem is that all the dashes are converted to questions marks ("?")
I?am trying to get the dashes back using:
mydf <- data.frame(lapply(mydf,function(x) replace(mydf,"?"(x),"-")))
but isn't working. I also tried:

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

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):

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.

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
David

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:

What is the best way to loop over an ALTREP vector?
Sorry for post a lot of things, for the first part of code, I copied my C++
iter macro by mistake(and you can see an explicit type casting). Here is
the macro definition from R_exts/Itermacros.h
#define ITERATE_BY_REGION_PARTIAL(sx, px, idx, nb, etype, vtype, \
strt, nfull, expr) do { \

[LLVMdev] Calling functions across modules. And those pesky vectors!
Before I get started with more questions, thanks for the prompt reply on
my last set question, that was much appreciated.
First, I found references to lazy inling and optimizations for calling
functions across modules, but I can't figure out how to do that. If I
just take a Function* that I got out of one module and call it from the
other, it doesn't work. What's the general

Hmisc-xtable label
Dear all:
Does anybody know about label conflicts between xtable and Hmisc? I found a couple of e-mails similar to this problem but is not clear to me how to get around the label problem.
The first table(longtable below) is generated with the latex function from Hmisc but for some reason when I try to hyperlink to it,it takes me to the top of the document. The second table created with the xtable

What is the best way to loop over an ALTREP vector?
Hi Bob,
Thanks for sending around the link to that. It looks mostly right and looks
like a useful onramp. There are a few things to watch out for though (I've
cc'ed Romain so he's aware of these comments). @romain I hope you taake the
following comments as they are intended, as help rather than attacks.
The largest issue I see is that the contract for Get_region is that it

Unexpected behavior when using macro to loop over vector
Hi all,
I found an unexpected behavior when I was trying to use the macro defined
in "R_ext/Itermacros.h" to loop over an atomic vector. Here is a minimum
example:
C++ code
```

#define GET_REGION_BUFSIZE 2
//Redefine the macro since C++ is not happy with the implicit type
conversion
