Limitations and scale of R, and performance issues if and when limit reached
Hi there
Thank you for everyone's help in all my previous questions.
By way of intro, I am a masters student in actuarial science at the
University of Cape Town, and I am doing a project in R on some healthcare
cost data. Just for clarity before I embark on further research may I please
ask the following.

Hypothesis test
Dear colleague:
Actually that is what is done.
When using the z-test between proportions in two different groups, or using
chi-squared to test the null hypothesis of equal proportions of two or more
groups, the null hypothesis is that
H0: p1=p2=p3.....=p
where this p is the pooled proportion, the proportion in the summed groups =
n1+n2+n3+..../N1+N2+N3....
in the z-test between two

question on why Rigroup package moved to Archive on CRAN
Hi,
Who should I ask about my package Rigroup_0.83 being moved to Archive status on CRAN and no longer available via install.package? I have no problems with the move if this was simply because of low demand. However, if there was a build issue with the newest releases that caused problems, I would be happy to address it. I'll just ask my students to install it from my own locally hosted

Interpretation of t.test results
I have run a t.test in R, and received these results:

pairwise.t.test vs. t. test
Hi,
If I set the p.adjust="none", does it meant that the output p values from the pairwise.t.test will be the same as those from individual t.tests (set var.equal=T, alternative="t")?
I actually got different p values from the two tests. See below. Is it supposed to be this way?
Thanks

Modifying Model Output
Hi!
I''m a very-very new Ruby-on-Rails user even if I have some experience
with other Languages (mostly PHP, so this is my first real
object-oriented language)
My problem, newbie-ish as it is, is the following: I have a model,
Article, that returns Articles from the DB. Now, when a certain field of
the model (the intro text) contains no data, I want to fill it with a

heplot3d / rgl : example causes R GUI to crash

wilcox.exact function (PR#8856)
Full_Name: Patrick Hodgson
Version: 2.0
OS: solaris 2.9
Submission from: (NULL) (65.94.128.161)
The value reported for the parameter W in the function wilcox.exact appears to
be incorrect. I have checked the reference in the help file for this function
(Myles & Hollander 1973, as well as 2nd ed. 1999 by same authors) and it is
clear that W is the sum of the ranks of the data set with the

t-test bootstrap versus permutation question
Hi,
I have a little problem that puzzles me about contradictory results returned
by a bootstraped t-test (as in MASS 3rd ed p. 146) versus a permutation
t-test (as in MASS 3rd ed, p 147).
Data are measurements done on 100 cells in 9 slides of fish blood. With one
method, cells are randomly sampled, and with the other method, the operator
selects cells arbitrarily (in a way it is done usually

how to interpret t.test output

Hello. I am still a newbie in R. Excuse me if I am asking something obvious. My efforts to get an answer through browsing the mailing archives failed. I want to perform an augmented Dickey-Fuller test and to obtain AIC and BIC and to be able to impose some linear restrictions on the ADF regression so as to decide the correct order of autoregression. However I could find no obvious way to impose

you can help me...

IceCast 2.2 MP3 stream and Real Player noise
I tested it this morning and here are my findings:
1) The Intro tag causes Real Player to give an error that the stream
"contains unexpected data and may be corrupt". It does not play with the
Intro tag in the mount point. If I remove the Intro tag the stream plays,
and, the Real Player noise caused by meta-data is gone and the meta-data
updates work.
2) The Intro plays in iTunes and
