Hello, the k-means {stats} help and the Hartigan&Won paper say nothing about the way random sets works (parameter nstart). I would expect to get the different results for each random initial set but I always obtain only one...

Thanks a lot Bill! This works fine! Useful to know regarding subset. Charles -- View this message in context: http://r.789695.n4.nabble.com/mlogit-message-invalid-row-names-length-after-subsetting-data-tp4684465p4684470.html Sent from the R help...

Hello, I would like to transform a contingency table (A x B) into a data frame while keeping the cross-tabulation structure (i.e. rows = levels of A, columns = levels of B). I have tried as.data.frame, xtabs, etc...

How can I draw a 3D perspective of a contingency table, that is showing 3D bars whose height is in proportion of the table cells? --------------- Charles RAUX, Laboratoire d'Economie des Transports CNRS-Universit? Lumi?re Lyon 2-ENTPE email...

I used in previous versions of R (R 1.1) to plot axes on projections of factorial coordinates using the function plaxes. This doesn't exist any more. Why this change ? No alternative ? --------------- Charles RAUX, Laboratoire d'Economie des Transports...

I am trying to restart on R after 2 months stop. Start with previously functioning procedure: "ch<-odbcConnect("dBase Files")" get "Warning message: ODBC connection failed in: odbcConnect("dBase Files") " I have tried unsuccessfully different working directories. The only change...

I don't find whether in multiv or mva package any output of "quality of representation" that is square cosinus of angle of each point (rows, and columns in correspondence analysis) with eigen factors. Before writing my own function, is...

I want to get subsets averaged on numeric variables number 5:13 but I get the error below that I cannot understand. > is.factor(dat$Statut) [1] TRUE > s<-ave(dat[,5:13],dat$Statut) Error in [<-.data.frame(*tmp...

I use hierclust (hierarchical clustering) in multiv package. In the documentation it is said that plclust (plotting a dendrogram) is available in S-plus. Can I find it anywhere (I have searched through http://lib.stat.cmu.edu/S and...

After searching in R- Introduction, FAQ, help... I don't understand this: I write a function in a file (.R): tt <- function(mc) { date() mc<-read.csv2("machines.txt",na.strings="") date() } I source it in R and I type...

3 general questions: 1) How can I have the plot History Recording automatically turned on each time I start R (Windows)? 2) How can I have some libraries automatically loaded at R start? 3) As far as I know weights...

Hi! I have been working a while with mlogit, estimating successfully a series of models. This time I have a series of discrete choice experiments with different effects to test (var Effect). I use the code below: when I estimate...

A disturbing behaviour of R: an import of data using RODBC library (Windows 98, R 1.1.1) recognizes accented characters in variables names but these can't be manipulated further. See below: > library(Rodbc) > ch<-odbcConnect("Paradox Files") > pollut...

Some naive questions: 1) How to remove a column in a data frame? I expected that rm would work but this is not the case (e.g. rm(dat$yyy) gives Warning message: remove: variable dat$yyy was not found...

I have made a cut of a numeric vector and try to plot it. However only half of the x-axis annotations (the labels) appear on the plot, apparently because of the font size. I have tried cex.lab, cex...

Sorry my question was *not* about getting the html help pages on *my* computer with R installed but to indicate to (distant) colleagues (and anyone interested) a *web* online help describing the richness of R with all the contributed packages...

Thank you for the hint (I didn't know makename). In fact contrary to what is indicated in help makename doesn't give legal R names (at least under Windows). See below: > make.names("a?a?a?a?????") [1] "a...
