similar to: model-based clustering

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

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

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

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

Hi, I want to use (similar to) las options in lattice (bwplot) plot. Actually I want to have x-axis labels as vertical instead of default horizontal. Thanks in advance for your help. Mahbub

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

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: > methods(predict) ... deleted lines ...

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

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

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

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 Murad Nayal wrote: > > Hello, > > I am rather new to R. in trying to use the hist() command I get behavior > that is somewhat puzzling me, in short,

Dear R-users, I have sent another mail some hour ago about a matlab Code I was trying to translate in R. Actually I have found a simpler code originally written in S-PLUS for the same function.

This is very OT. If list readers can point me in the right direction, to other mailing lists, or web sites for recommended databases, that will be much appreciated! My wife's doctor wants to move records, for approximately 6000 patients (over a 12 year period), from paper (18th century) to a database (20th century). The data entry will be a PITA, for his secretaries, regardless of what

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. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Today I updated to trunk the toolchain for my work developing on Cortex-M4F. I was super excited to see three commits by Tim Northover that actually attempt to improve the machine code generation for my target, or any ARM target for that matter (as opposed to other important work on compiler correctness or architectural elegance or formatting comment white-space, I mean). Is he alone or are
