Integrating R-programs into larger systems
Hi experts!
Have anybody experience in including an R-program
as part of a larger system? In Matlab there is a toolbox
that converts a m-script into C-code.
One application in mind is that I do the model building in R,
for estimating the risk for cancer based on clinical measurements.
When the model is ready, a small R-program can simulate
the model to estimate the risk for a new patient. The

Expert systems
Hi R-users
Is there any functions in R that can implement "expert systems"?
The aim of an expert system is to produce a probable diagnosis
for a patient with certain symptoms.
In the classical expert system a mumber of "experts" are asked to make
"statements" on the probabilities for different diseases when a
combination of systems would appear. One typical

Siegel-Tukey test for equal variability (code)
Hi, I recently ran into the problem that I needed a Siegel-Tukey test for
equal variability based on ranks. Maybe there is a package that has it
implemented, but I could not find it. So I programmed an R function to do
it. The Siegel-Tukey test requires to recode the ranks so that they express
variability rather than ascending order. This is essentially what the code
further below does. After the

In the sem-package

As a simple example I take an ordinary factor analysis.

Nelson- Siegel - (Yield Curve - Smoothening of curve)
I am Julia Cains from Brisbane. This is my
first mail to this group and I have recently started learning the R language.
I am trying to learn the smoothening
of the yield curve. However, I came across the CRAN package – “YieldCurve”
meant for Modelling and estimation of the yield curve. The problem is I am not
able to understand whether this package will help me to carry out smoothening of

Modelo de Nelson y Siegel
Hola a todos: En la estimación de parametros de Nelson-Siegel vienen definidos 3 argumentos: rate, maturity y MidTau. Este último lo define como un vector el cual indica el término medio del vencimiento para maximizar el factor beta2.Si yo tengo un vector de maturity de 77 datos, la pregunta es:¿Qué tan importante es el argumento MidTau, y qué otra especificación tiene? no me queda muy claro cómo

Prompt comes too late
Hi R fans
I am trying to make a program to ask the user to choose data file:
print("Choose data file please !")
matr=read.table(file.choose(),dec=".",header=TRUE)
The problem is that the prompt
Choose data file please !
comes after I have chosen the file.
What am doing wrong?
Thanks in advance

stats::line() does not produce correct Tukey line when n mod 6 is 2 or 3

Ah well, I can't get it for a week. But the fact that it's often called
Tukey's three group line (try a search on *tukey three group line* and
you'll get plenty of hits) is pretty much a giveaway.

Anova and tukey-grouping
Hello,
I am really new to R and it's still a challenge to me.
Currently I'm working on my Master's Thesis. My supervisor works with SAS
and is not familiar with R at all.
I want to run an Anova, a tukey-test and as a result I want to have the
tukey-grouping ( something like A - AB - B)
I came across the HSD.test in the agricolae-package, but... unfortunately I

Tukey HSD following lme
Hi everyone
I'm using Tukey HSD as post-hoc test following a lme analysis. I'm
measuring hemicelluloses in different species treated with three
different CO2 concentrations (l=low, m=medium, h=high). The whole
experiment is a split-plot design and the Tukey-function from the
package multcomp is suitable for lme-analysis with random factors.
The analysis works fine but I get a non

Is using glht with "Tukey" for lme post-hoc comparisons an appropriate substitute to TukeyHSD?
Hello,
I am trying to determine the most appropriate way to run post-hoc
comparisons on my lme model. I had originally planned to use Tukey
HSD method as I am interested in all possible comparisons between my
treatment levels. TukeyHSD, however, does not work with lme. The
only other code that I was able to find, and which also seems to be
widely used, is glht specified with Tukey:

stats::line() does not produce correct Tukey line when n mod 6 is 2 or 3
The problem or actual R implementation relies on an assumption
that median(x[i] | x[i] <= quantile(x, 1/3)) == quantile(x, 1/6)
which reveals not to be true despite very trustful appearance.
If we continue with the example of x=y=1:9
then quantile(x, 1/6)=2.5 (here quantile() is taken in C-code sens, not R's one)
while median(y[i] | x[i] <= quantile(x, 1/3))=2

How can i implement Tukey linear test in R?

GLM with tweedie: NA for AIC
Dear R users;
I am modelling densities of some species of birds, so I have a problem with a great ammount of zeros.
I have decided to try GLMs with the tweedie family, but in all the models I have tried I got an NA for the AIC value.
Just to check the problem I've compared the a glm using the Gaussian family with the identity link and a glm using the tweedie family with var.power=0 and

I have been trying to do tukey's test to no avail. This is what I have
and the error produced:
pen.df = data.frame(blend, treatment, y)

Error in tukey.1(aov.pen, pen.df) : the model must be two-way
This is a two-way design. Therefore I am confused. Can anyone help?
