Re: ESS & R data import problems
I have a similar question, I know about --vsize, but I use R under Emacs
using ESS. I know there is an easy way to call R from ESS with command
line options but I don't remember how. I can't find help on this in ESS
documentation or in R documentation.
Could someone please remind me how this is done.

anova question
I have a probably very naive question about the R anova/aov functions:
I've found in several text books with descriptions of anova procedures
that, in nested anova (specifying the model "X~A/B", B being a factor
specifying treatments, and A groups of samples within each treatment),
the mean square for "among treatments" is divided by the mean square
"within treatment

R data import problems
Excuse me, if the following is FAQ or nonsense, I'm new to R (and the
list)!
After trying to import a textfile of 184897 Bytes, R (v0.63.0 on Linux
2.0.35/DLD 5.4) gives the following error message:
> read.table ("db.out")
Error: heap memory (1953 Kb) exhausted [needed 150 Kb more]

Power of tests
Hello R-Experts,
2 questions:
does anybody have example functions for determining the power of,
say, a t-test or a single factor anova with fixed or random factors?
and: is there an implementation of Cochran's test for heterogeneity
of variances (i.e., is there a frequency distribution of Cochran's
C)?
Many thanks for your attention ...

problems compiling R packages with Linux
Hello out there,
my first try to install a package (e.g. ctest from CRAN) didn't
succeed; looking at the error messages I think it must be a
configuration problem of my machine, but as I'm not very experienced I
would be glad if someone could give me a hint ...
R's version is 0.63.0, my i386-Linux is kernel 2.0.35. I hadn't had
problems to compile R, and R itself seems to work.

time series analysis
Hello out there,
in their "R Complements" to Modern Applied Statistics W. Venables and
B. Ripley say that there is a lack of time series related functions in
R compared to S plus. Looking at CRAN I didn't find much, too. As I
have to learn something about +-basic ts analysis, e.g. spectral
analysis, I would like to know whether somebody has developed a

ANOVA "ex post" Analysis
Hello everybody,
shame on me if I have overlooked something (CRAN, StatLib), but I think
I've searched carefully. Maybe it's just too obvious to see for me
(happens frequently).
Is a function available that extracts multiple comparison of means from
objects produced by "aov()" ? Sorry if the term is not correct, I

readline() for passwords?
I don't like to have my password exposed by typing at all. I also don't like
to enter it each time that I wish to open a database (or when I run scripts
automatically across a Linux cluster). My solution has been to keep a file
in my HOME directory containing the username and password for the databases.
This file has read and write permission set so only I (and root) can read
it; this is

what does the within component of varcomp (ape library) output indicate?
I am trying to use varcomp to obtain the variance partitioning across
different nested levels of random effects (say x,y and z). I get the
three variance components (for each of my along with an additional one
called 'within' from varcomp output. I am using the 'scale total
variance to 1' option and though the within component is small, it

Johannes Huesing sent a message to stat-lisp-news at stat.umn.edu

Can anyone summarize what was said about R in the article? If there

how to extract individual values from varcomp?
Hi
try
str(varcompobject)
to see structure of this object. You can extract parts by standard R means.

how to extract individual values from varcomp?
Hello,
I am trying to use varcomp to decompose the variance across multiple
nested levels on a lme object. I am able to successfully do this and
when I view the varcomp object I can see the individual values /
estimates for the variance at different levels.
However, I want to be able to extract each of them separately, as I
need to build a confidence interval using bootstrapping on the sample

Hi all
I am trying to generate a normal unbalanced data to estimate the coefficients of LM, LMM, GLM, and GLMM and their standard errors. Also, I am trying to estimate the variance components and their standard errors. Further, I am trying to use the likelihood ratio test to test H0: sigma^2_b = 0 (random effects variance component), and the t-test to test H0:mu=0 (intercept of the model Yij = mu

Extract Variance Components

I'm still having problems putting the variance components of my model in to
a data frame, it is a continuation of this discussion,

on the problem of extracting variance components. I have got my mixed
