Summary of translation status
Dear R-devel & Translation Teams,
In order to monitor the progress of the translation for the
pt_BR team I wrote a script to summarize the status of the translations.
It wasn't difficult to extend it to the other languages so I decided to
set up a page with the summaries of the translation for all languages
for which currently exist a translation.

Bartlett's Test of Sphericity
Hello Dear R user,
I want to conduct a Principal components analysis and I need to run two
tests to check whether I can do it or not. I found how to run the KMO
test, however i cannot find an R fonction for the Bartlett's test of
sphericity. Does somebody know if it exists?
Thanks for your help!

R_PROFILE on Windows
Dear R-devel,
There seems to be a bug in the Startup section, regarding the
R_PROFILE environment variable in Windows. If not a bug in the Startup
itself, perhaps a bug in the documentation.
According to ?Startup:
Then R searches for the site-wide startup profile unless the
command line option '--no-site-file' was given. The name of this
file is

Problem in 'methods' package (PR#4525)
Full_Name: Fernando Henrique Ferraz Pereira da Rosa

OS: Linux 2.4.21
Submission from: (NULL) (200.206.211.169)
After installing R 1.8.0, the R DBI interface stopped working. I tracked it
down as a problem in the 'methods' package, that comes in the default
installation.
Somehow the function '.valueClassTest' which is defined on package

SAS to R migration questions
Hi,
I'd like to get away from SAS, but I don't really know R well enough at
this point to know if it would be good for this project. I tried to
describe the essence of the project below without getting bogged down in
details.
It starts when I receive a data flat file. There's lots of columns, but
the relevant ones are:
custid (customer ID number)
saledt (date of sale)

Contrast matrices for nested factors
Hi, I'd like to know if it's possible to specify different
contrast matrices in lm() for a factor that is nested within another one. This
is useful when we have a model where the nested factor has a different
number of levels, depending on the main factor.
Let me illustrate with an example to make it clearer. Consider
the following data set:
set.seed(1)

Adjusted p-values with TukeyHSD (patch)
Dear R-developeRs,
Attached follows a patch against svn 34959 that adds the
printing of p-values to the TukeyHSD.aov function in stats package. I
also updated the corresponding documentation file and added a 'see also'
reference to the simint function of the multcomp package.
As it was already brought up in a previous thread [1] in R-help,
one can obtain the adjusted

VIM Syntax Highlighting
Has anyone got vim to have syntax highlighting with R function codes? I
know there's something similar that works with emacs (ESS or something like
that), but I was wondering if anyone knew an equivalent that worked with vim.
Thank you,

Difference between two correlation matrices
Hi
Now a more theoretical question. I have two correlation matrices - one
of a set of variables under a particular condition, the other of the
same set of variables under a different condition. Is there a
statistical test I can use to see if these correlation matrices are
"different"?
Thanks

Portuguese translation problem (PR#13756)
Full_Name: Adriano Azevedo Filho
Version: 2.9.0
OS: Windows Vista
Submission from: (NULL) (201.68.79.62)
The error message produced when the function name typed in the console is
misspelled in the Portuguese translation. This is not a new issue but as it is
around for sometime I've decided to report. As this is a frequent message when
beginners start using R, it gives an unfortunate bad

Mixed effects model help
I am attempting to set up a mixed effects model, with one factor fixed (put
in as.factor, with three factor levels) and one factor random(put in
as.factor, with four different batches) as well as the interactions. I have
tried the lme function, but R continues to crash everytime I run it...
My code is:
model_lme(y~a,random=~b+a:b)
Is this way off base?
I just need to get F statistics to do

lattice graphics empty in Sweave
Hello,
I have problems using lattice graphics together with Sweave under
Windows XP and R 2.0.0; 2.0.1 Patched; 2.1.0 devel respectively.
Base graphics are o.k., but for lattice graphics empty files (.eps and
.pdf) are generated.
The only workaround I found was to write and read the respective figures
explicitely using postscript() and includegraphics{}.
Have I missed something to solve this

Weird options(digits=n) behaviour
I noticed some very weird behaviour of the function: options(digits=n),
where n is the number of digits you would expect to get in R calculations.
Let's take a example:
> options(digits=4)
> getdata(caso.pool.k3.r3.e2)
[1] 6.053 2.641 -3.639 14.259 6.082
Which works fine... now, trying again, with different data:
> options(digits=4)
> getdata(controle.pool.k3.r3.e2)

Two factor ANOVA in lme
I want to specify a two-factor model in lme, which should be easy?
Here's what I have:
factor 1 - treatment FIXED (two levels)
factor 2 - genotype RANDOM (160 genotypes in total)
I need a model that tells me whether the treatment, genotype and
interaction terms are significant. I have been reading 'Mixed effects
models in S' but in all examples the random factor is not in the main

Goodness of fit tests
I have a dataset which I want to model using a Poisson distribution, with a given parameter. I would like to know what is the proper way to do a ''goodness of fit'' test using R.
I know the steps I''d take if I were to do it ''manually'': grouping the numbers into classes, calculating the expected frequencies using ''ppois'', then

Paste and namespace
Hi, my doubt is very simple. I'm sure I've seen someone using something
like this before, but unfortunatelly my searches in the archives were useless.
Well, I have some objects called after a name that has a number attached to
it,
varying. Let's say I have:
> ls
poly1 poly2 poly3 poly4 poly5 poly6 ...
I would like to access these objects using a for(), in which I could do

Subseting by more than one factor...
Is it possible in R to subset a dataframe by more than one factor, all at
once?
For instance, I have the dataframe:

Paths for Shell Scripts called from R
Hello list,
I suspect this is more a linux question than an R question, but I'll describe my situation in case
anyone here knows of an elegant solution.
I'm using Sweave and R to create thousands of customized reports. Within an R loop, I have R create
a table.tex file using the CAT function which, for each iteration, creates a unique table.tex file in
a subdirectory of the directory
