Tukey multiple comparisons
I am embarrassed to have to ask this but can anyone tell me of a Tukey
multiple comparisons procedure available for R? I have looked through
the search page, through the FAQ, and in the index of V&R (1999), and
I still can't find such a thing. I see there is a ptukey function and
a qtukey function but that is as far as I got. Do I need to roll my
own?

Perl on Windows XP for Rcmd build
Is there a recommended binary version of perl to use under Windows XP
for `Rcmd build'? The R FAQ for Windows just mentions "perl". I
think that Kevin Wang's document on R for Windows suggests ActiveState
perl but I have not been able to install it.
I am running Windows XP Professional on a laptop. The operating
system was originally Windows 98 then upgraded to Windows ME

entropy problems IRIX
Hello!
I am running openSSH 2.9x on an IRIX 6.5.x platform.
This was recently installed using SGI-supplied
"freeware" binaries.
I find that as time goes on, it takes more attempts
to establish an ssh connection from the IRIX platform
to another machine, as it fails with "not enough entropy
in PRNG." I posted a note asking for assistance, and
received a reply suggesting I

R-beta: updating the library index / overriding compile options
Would it be possible to include a new command in the ${RHOME}/etc path, which
updates the Library index (Rd and html) via "R LIBINDEX".
I need it because I use RPM to manage three different R installations (at home,
at the institute and in the seminar rooms). I put all libraries into several
packages, so it is easy for me to update a single library at all these
different places.

Debian packages for R-1.3.0
I have installed the binary packages for Debian GNU/Linux release 2.3
(woody) in the U.S. mirror of the CRAN archive. They should propagate
to the main CRAN archive within a day and to the other mirrors within
two days.
These packages have been compiled with gcc-3.0 and g77-3.0. I believe
the testing distribution currently provides only a snapshot of
gcc-3.0, not the latest released version, so

creating a grid of function values
I want to create a grid of function values for use in `contour' or
`persp'. The function is the log-likelihood for the gamma. The
sample is stored as vector of length 20 called `Survival'.
A single evaluation of the log-likelihood at, say, scale = 9 and shape
= 10 would be obtained by
sum(dgamma(Survival, scale = 9, shape = 10, log = TRUE))

lme: anova vs. intervals
Windows 2000 (v.5.00.2195), R 1.5.1
I have an lme object, fm0, which I examine with anova() and intervals().
The anova output indicates one of the interaction terms is significant, but
the intervals output shows that the single parameter for that term includes
0.0 in its 95% CI. I believe that the anova is a conditional (sequential)
test; is intervals marginal or approximate? Which should I

Large data sets and aggregation
I've noticed quite a few messages relating to large data sets bedeviling
R users, and having just had to program my way through one that actually
caused a "Bus error" when I tried to read it in, I'd like to ask two
questions.
1) Are there any facilities for aggregation of data in R?
( I admit that this will not do much for the large data set problem
immediately)
2) Is there any

Variance-covariance matrix for beta hat and b hat from lme
Dear all,
Given a LME model (following the notation of Pinheiro and Bates 2000) y_i
= X_i*beta + Z_i*b_i + e_i, is it possible to extract the
variance-covariance matrix for the estimated beta_i hat and b_i hat from the
lme fitted object?
The reason for needing this is because I want to have interval prediction on
the predicted values (at level = 0:1). The "predict.lme" seems to

Multilevel analysis with package lme

About that i have one general and one specific question.
This is what i have copied from the help-file on lme:

NLME: gls parameter evaluation inconsistency (PR#4757)

Decreasing my personal entropy ...
R-Listers:
A very minor -- and maybe silly -- question just for personal enlightenment.
In S (either R or S-Plus, AFAIK) when one types or pastes a trellis graphics
command into the commands/console window, the graph is automatically
produced:
e.g.,
trellis.device(...)
xyplot(y~x)
If one puts these in a function and calls the function, the same occurs.
However, if one sources in these command

Access to cran.us.r-project.org
I am the maintainer of one of the CRAN mirrors in the U.S.,
cran.us.r-project.org. It appears that this site has been
inaccessible since Friday.
This has me puzzled because I can connect to the same machine through
ssh and I can see that the http daemon (apache) is running. In fact I
can make an http connection from this machine to this machine and from

Singular Gradient in nls
//Referring to the response posted many years ago, copied below, what
is the specific criterium used for singularity of the gradient matrix?
Is a Singular Value Decomposition used to determine the singular
values? Is it the gradient matrix condition number or some other
criterion for determining singularity?

looking for Prof Bates' file
Hello
I'm reading up on fitting truncated Weibull distribution to data.
There are posts in 2002 that point to this presentation by Prof Bates:
http://www.stat.wisc.edu/~bates/JSM2001.pdf
but now the file is not there. I can't find it anywhere else, Google
doesn't have a cached copy for it.
Could someone please give me a copy of this file, if they have it?
Thanks and regards,

confidence interval too small in nlme?
Hello,
I am interested in using nlme to model repeated measurements, but I don't seem
to get good CIs.
With the code below I tried to generate data sets according to the model given
by equations (1.4) and (1.5) on pages 7 and 8 of Pinheiro and Bates 2000 (having
chosen values for beta, sigma.b and sigma similar to those estimated in the
text).
For each data set I used lme() to fit a model,
