Access web content from within R
Hi,
I have to search in an online db for registered manufacturers of raw
materials.
Can I use R for the following:
I have a list with monograph numbers eg: l <- c(198, 731,355)
Now I want to make a dataframe, containing the monograph number and the
information listed under COS:
Certificate holder, certificate number, Status, Type
Is this possible with R?
kind regards
Bart

OT: Monograph on Statistical Programming
Dear all,
my question might be a bit off-topic.
Is there anything like a standard textbook on statistical programming?
With that I don't mean anything like MASS, S Programming, Programming
with Data, ... (no offense meant, they are fantastic books and each of
those three helped me a great deal).
Rather in the direction of the "Numerical Recipes" Series addressing how

subset selection for logistic regression
R-packages leaps and subselect implement various methods of selecting best or
good subsets of predictor variables for linear regression models, but they do
not seem to be applicable to logistic regression models.
Does anyone know of software for finding good subsets of predictor variables for
linear regression models?
Thanks.

Order-restricted inference
Hello,
I looked for R packages which focused on order-restricted statistical
inference, but I could find only the isoreg() function.
I would need to test whether the means in my (repeated measures) data follow
a given order, e.g. A<B=C<D.
I took a look at the monograph by Barlow et al. (1972) on this topic and
found that for my case the null hypothesis is always A=B=C=D. This might be

When I consider how to organize this data my first thought is to generate an HTML file with links to the R-generated plots, which HTML file organizes the plots in the required

education task view
Dear R-Devel,
I have had it in my mind for some time now that a Task View related to
R and education might be a good thing.
There are currently 19 Task Views, covering a broad spectrum of
general topics for which R may be used. The homepage lists 64 books
related to R, and several of them have accompanying packages on CRAN.
There is a wiki and a host of contributed documentation. We also have

Mixed ANCOVA with between-Ss covariate?
Hi all,
I have data from an experiment with 3 independent variables, 2 are
within and 1 is between. In addition to the dependent variable, I have
a covariate that is a single measure per subject. Below I provide an
example generated data set and my approach to implementing the ANCOVA.
However the output confuses me; why does the covariate only appear in
the first strata? Presumably it should

Goodness of fit test for estimated distribution
Hi,
is there any method for goodness of fit testing of an (as general as
possible) univariate distribution with parameters estimated, for normal,
exponential, gamma distributions, say (e.g. the corrected p-values for
the Kolmogorov-Smirnov or Chi-squared with corresponding ML estimation
method)?
It seems that neither ks.test nor chisq.test handle estimated parameters.

predict.arima
Hi *,
Firstly, thank you so much for your time to read my email.
I am currently interested in how to use R to predict time series from
models fitted by ARIMA. The package I used is basic stats package, and the
method I used is predict.Arima.
What I know is that ARIMA parameters are estimated by Kalman Filter, but I
have difficulty in understanding how exactly maximum likelihood (ML)

help in plotting
Dear list,
I want to combine several plots in one graph.
I did this: plot(a1); plot(a2, add=TRUE); ...plot(a5, add=TRUE)
The problem is the more plot we put, the more complex the graph.
Is there any way to label each line; or other way just to make sure I know
which one which?
Thank you for the help,

GLM available book recommendation
Howdy,
I looked at the references in the R and S-Plus literature to find a
good introduction/reference to GLM. When I then went to Amazon it
seemed to me that all the recommended books are out of print.
Can anyone give me a recommendation which _available_ book to get?

Comparing GAMMs
Greetings!
I am looking for advice regarding the best way to compare GAMMs. I
know other model outputs return enough information for R's AIC, ANOVA,
etc. commands to function, but this is not the case with GAMM unless one
specifies the gam or lme portion. I know these parts of the gamm contain
items that will facilitate comparisons between gamms. Is it correct to
simply use these values

new book
Just thought I would mention that there is a new O'Reilly book out,
"Developing Bioinformatics Computer Skills", which is ok, pretty
superficial about some things but at least it lets you know what is
