how to contrast with factorial experiment
Hello, R experts,
If I understand Ted's anwser correctly, then I can not contrast the
mean yields between sections 1-8 and 9-11 under "Trt" but I can
contrast mean yields for sections 1-3 and 6-11 because there exists
significant interaction between two factors (Trt:section4,
Trt:section5). Could I use the commands below to test
the difference between sections 1-3 and 6-11 ?

Fractional Factorial - Wrong values using lm-function
Hello.
I'm a new user of R, and I have a question regarding the use of aov and
lm-functions. I'm doing a fractional factorial experiment at our production
site, and I need to familiarize myself with the analysis before I conduct
the experiment. I've been working my way through the examples provided at

Design and analysis of mixture experiments
Hi,
I'm interested in experimental design and data analysis on mixtures, like
cake recipes where the sum of the components is fixed; e.g.
<http://www.itl.nist.gov/div898/handbook/pri/section5/pri54.htm>.
I can't believe that R doesn't have facilities to design and analyse such
experiments, but I haven't been able to find them (I have looked quite
hard!). Can anyone point

How can I link/anchor down the page with #anchor in urls?
I''m trying to expand on a blog tutorial and one thing I can''t figure out
is how to use anchors within pages.
For example say I have sections on a page with anchors like <a
name=section1"</a> through <a name=section6"</a>. Using older non-rails
methods I would construct urls that contains the pound symbol and anchor
name in the url such as

Modelo senoidal de datos temporales de radiación y prueba de Thom
Hola a todos:
Estoy intentado realizar un modelo senoidal de unos datos de radiación
solar con el fin de afrontar el relleno de la serie y aplicar la prueba
de Thom para verificar su homogeneidad [0].
De momento me encuentro con los siguientes problemas:
1- ¿Existe la prueba de Thom en R? ¿O debo crearme mi propia función?
2- Para la realización del modelo senoidal estoy siguiendo los pasos

Scheffé's method?
Evidently my RSeek capabilities have once again failed me...By any chance is Scheffe's method (http://www.itl.nist.gov/div898/handbook/prc/section4/prc472.htm) implemented independently in any R base packages? If not, is it implemented independently in any of the add-on packages?
Thanks again for any insights.

FW: computing a p-value ...
Thanks to Rolph Turner and Jason Turner ...
I guess I was too excited about getting back on the list after an absense of
several years ... I'll be a little more thoughtful about the problem before
posting next time, and a little less trigger-happy with the "Send" e-mail
button.
Never-the-less, much appreciated.

NLS sensitivity to start= values or poles in data range
Greetings R-help! I'm fairly new to R and am trying to expand my knowledge beyond using R for simple summary statistics and basic tests. To that end I am attempting to write an interactive R-script that will perform a general rational function fit to a given dataset based on the example given at http://www.itl.nist.gov/div898/handbook/pmd/section6/pmd64.htm.
The problem that I seem to have

stationarity tests
How can I make sure the residual signal, after subtracting the trend extracted through some technique, is actually trend-free ?
I would greatly appreciate any suggestion about some Stationarity tests.
I'd like to make sure I have got the difference between ACF and PACF right.
In the following I am citing some definitions. I would appreciate your thoughts.

passing constrasts=FALSE to contrast functions -- why does this exist?
Hello,
I've noticed that all contrast functions, like contr.treatment,
contr.poly, etc., take a logical argument called 'contrasts'. The
default is TRUE, in which case they do their normal thing of returning
a n x n-1 matrix whose columns are linearly-independent of the
intercept.
If contrasts=FALSE, they instead return an n x n matrix with full rank
(usually the identity matrix,
