As I wrote before: This calculates appropriate x-values for grouped barplots, "x" being the matrix of interest. Not elegant but it works. cumsum(array(c(1,rep(0,dim(x)[1]-1)), dim=c(1,length(x))))+0:(length...

Hi everybody ... I have to perform Hotteling's T^2 Test - more generally a MANOVA - on a set of data. Is there a (simple?) possibility to do it in R? The somewhat obvious way to do it would be > summary...

Hello everybody, I frequently have to produce barplots from variables the natural variation of which is far away from zero. A typical range would be, say from -16 to -28. So, the following example should give an "honest" presentation: x...

Karamian, have a look at "help(memory)" ... You can enlarge the memory reserved for R by specifyng the command line arguments "--vsize" and "--nsize". When using ESS, type "C-u M-x R" and ESS will prompt for arguments passed...

Karamian, R provides the possibility of perspective plots, which are one kind of 3D graphics. Look at the documentation for "persp()", or just type "example(persp)". On the other hand there is a extremely powerful software package named "xgobi" which...

# Peter B. Mandeville kindly offered to send me code for Hotelling's T^2 # Test. Unfortunately there seems to be no route to his machine. # So i'm trying to reach him via the Mailing List. ------------------------------------------------------------------------ Sir, this morning i...

Hello everybody, shame on me if I have overlooked something (CRAN, StatLib), but I think I've searched carefully. Maybe it's just too obvious to see for me (happens frequently). Is a function available that extracts multiple comparison of...

Hello everybody, since I installed R-0.90.0 (Linux 2.0.25) I have problems with generating printable output with 'help()'. Default output to the terminal ('echo $PAGER' gives 'less') works o.k.. When invoking 'help(topic,offline=T...

Troels, I think the problem is just that most of the plotting functions of nlme make heavy use of Trellis graphics (See paragraphs "Description", "Form" and so on in help(qqnorm.lme)). Trellis devices are not supported by R. Uli...

Ragnar, I had no problems in obtaining the book of Annette Dobson from a local bookstore. It is quite condensed in my opinion and gives a good introduction also for GLM-newbies (like me). A problem will be the weakness...

First of all, sorry for sending my stuff twice! Concerning my problems, thanks to Prof Brian Ripley now everything works fine. I really did not read the assumptions of the Fortran code carefully enough. That's when you start to...

Alexandre, "help(boxplot)" among other things says: Usage: ... boxplot.formula(formula, data = NULL, subset, na.action, ...) ... So you can use > boxplot(table$X ~ table$A,subset(table$B==given.value)) Any logical expression should work. Best ... Uli Flenker Institute of...

John, I'm not running R under hpux, but I have the same problem generally with the hpux terminal emulator ("hpterm"). For example I installed a GNU bash on our hpux (with the readline library statically linked) and the arrow...

I'm not familiar with S/S+, but I think the "xgobi" software package can do what you want (spin plots, brushing, etc. ...). There is an interface to R as well as to S/S+. The program itself and the...

Dear all, I have a problem formulating random effects when using the nlme package. ?nlme says that the random effects can be a formula or a list of formulae. But when trying to do so, I run into trouble. (R...

Do I remember correctly that SOMs are "self oraganizing maps" and are more or less identical to Kohonen networks? As far as I know there is no R package for that purpose. A widely used - at least in Germany - neural...
