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

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 -- Murad Nayal M.D. Ph.D.

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

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

help on barplot
Hello, I am trying to compare two histograms using barplot. the idea is to plot the histograms as pairs of columns side by side for each x value. I was able to do it using barplot before but I can't remember now for the life of me now how I did it in the past: > d [,1] [,2] -37.5 0.0000000000 2.789396e-05 -32.5 0.0001394700 5.578801e-05 -27.5 0.0019804742

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

Hi, I use lme to fit models like R> res1 <- lme(y~A+B, data=mydata, random=~1|subject) R> res2 <- lme(y~B+A, data=mydata, random=~1|subject) (only difference between these two models are the sequence in which the indep variables are written in formula) where y is continuous and A, B, and subject are factors.

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

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
