silhoutte.default bugs
Hello all,
This might have been fixed in later versions (I am using R1.7.0), r-help
archive contains messages reporting similar problems but no reports of
codes fixes. I have encountered a couple of problems using the
silhouette function. one occurs when the clustering contains clusters
composed of 1 element (Martin Maechler posted code few months ago that
fixes a similar problem that occurs

model-based clustering
Hello,
I was wondering whether a Poisson mixture modeler/cluster analysis
package is available for R. I scanned CRAN packages and couldn't find
anything but I thought I'd ask. If not could anyone recommend a non-R
open source package. I have found 'snob' but this program seems a bit
hard to use in an automated, non interactive fashion.
regards,
Murad

EMACS/ESS problems
Hello all,
since we're on the topic of R-editors. I am using emacs/ess on a unix
workstation (to interact with R and have been having a little problem. I
usually write the R commands I need to run in a separate buffer then
copy and paste them into the *R* buffer for evaluation. The problem is,
if any command is spread over multiple lines emacs/R hangs when I paste
it in the R buffer for

debugging non-visible functions
Hi,
I would like to step-through a non-visible function. but apparently I
don't know enough about namespaces to get that to work:

... deleted lines ...
[27] predict.rpart* predict.smooth.spline*
[31] predict.survreg.penal*
Non-visible functions are asterisked

CentOS-6.5 rescue disk?
Is there such a thing as a CentOS rescue disk?
Google gives many links to such a thing,
but when I pursue them I do not get to an URL
where I can actually download one.

[Fwd: curiousity with hist]
just realized that the bin value is actually the relative frequency
divided by the bin width. sorry for consuming band width.
Alas, is there anyway to make hist() calculate relative frequencies
irrespective of bin width?
thanks

anova model refinement/clustering question
Hi,
I am trying to refine models of a continuous response variable and a
number of categorical predictor variables. I know of some model
refinement tools available in R that help in the selection of model
terms like dropterm and addterm from MASS etc. However, I would also
like to try to refine the model by 'coalescing' some levels of some of
the predictor factors. Is there a standard

Formal definitions of R-language.
Hello!
Some CS-guys (the type who knows what Church formalism is) keep asking
me questions about formal definitions of R-language that I can not
answer (or even understand). Is there some freely available papers which
I can throw at them where it would be explained is R
functional/OOP/procedural language, does it use weak/strong,
dynamic/static typization, does it use lazy or ...(do not know

S-PLUS code in R
Dear R-users,
I have sent another mail some hour ago about a matlab Code I was trying to

Hi,
I want to use (similar to) las options in lattice

graphics reset
Hello,
Is there a specific command to clear the graphics window. On occasion I
need to construct plots using commands that don't clear the graphics
window (like text, lines and points etc.) -only- and hence need to clear
the graphics completely before hand.
also, is there a way to restore the graphics parameters to default
values, say in these cases where you forgot to save the original

SVM question
Hello all,
I am trying to use svm (from the e1071 package) to solve a binary
classification problem. The two classes in my particular data set are
unequally populated. class 'I' (for important) has about 3000 instances
while class "B" (for background) has about 20,000. experimenting with
different classifiers I realized that in cases where such an asymmetry
exists there is a

Multiple graph sheets
In Splus the code
test.lm <- lm(y ~ x, data = test.data)
plot(test.lm)
generates a graphics window that contains
multiple graph sheets that one may choose
from via the "page" tabs at the bottom of
the window.
Is there a way to do this sort of thing in
R? As another example, I have some repeated
measures data with continuous outcomes and
have been working with the nlme library in

Stepwise logistic discrimination - II
I apologise for writing again about the problem with using stepAIC +
multinom, but I think the reason why I had it in the first place is
perhaps there may be a bug in either stepAIC or multinom.
Just to repeat the problem, I have 126 variables and 99 cases. I don't
know if the large number of variables could be the problem. Of couse the
reason for doing a stepwise method is to reduce this
