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 see is that I am working with a new login account on the same machine.

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 found only quotations of plclust in multiv) or is it only part of the S package (which I don't have)? Thanks --------------- Charles RAUX, Laboratoire

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 only found to assign NULL value (e.g.: dat$yyy<-NULL). Is it the right way? 2) Is the place formerly occupied by dat$yyy automatically gained by R for other uses? 3) If t1 and t2 are 2 only

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*, , value = if (n) { : Argument "i" is missing, with no default Thanks in advance --------------- Charles RAUX, Laboratoire d'Economie des Transports

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 can be specified only for lm. How can I take account of weights with a weighted sample in other models or functions (table but also other multivariate and cluster techniques)? Thanks

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?

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 ?

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 tt(). The answer is > tt() [1] "Mon Aug 14 11:18:25 2000" > The instructions following the first "date()" are ignored. Why?

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.axis (what is the difference?) etc. The x labels are never printed whatever value I use from 0.0005 to 20. I can't obtain a way to make all the labels appear correctly. Between the short 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... and always got a "flattened" list of 3 variables (A, B, Freq). How to do that? Thanks in advance Charles Raux

Hi, Why this function doesn't work? function (x) { if (is.factor(x)) { if (!is.ordered(x)) { warning("La mediana non si puo' calcolare!!!") return(NA) } me <- median(unclass(x)) if (me - floor(me) != 0) { warning("Mediana indeterminata") return(NA) } else

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 result: how is it selected? Charles Raux

Dear all, Does any know how to solve PDE with R? The archive list refers to the use of ODE if PDE are parabolic. I am not a mathematician and this does not mean anything for me! help would be very appreciated.

Dear all, I am a SAS user, who's trying R. I am a little bit lost for graphics. What is the simplest way for plotting y as a function of x with one symbol (line or dot) for each level of a class variable z (for SAS langage= plot x*y=z). Can I add vertical bars for standard deviation stored in a separate variable (say ystd). Finally, is it possible to do all this with xyplot function

Bonjour, Je veux cherché l’estimateur de vraisemblance maximal (MLE)d’une fonction à 3 paramètre inconue étant donné une échantillon de taille 50 (les observations des valeurs de x) alors comment je peux procédé La fonction de densité est définie par : f(x)= 1/3(g(a1)+g(a2)+g(a3)) avec g(ai)=(exp(ai)*ai^x)/x! pour i=1,2,3.

hey people I'm new to the list and would like to say thanks to everyone that has worked on syslinux/isolinux. It's one of those tools that everyone uses at some stage but no-one ever really takes much notice of it - mainly because *it just works*. So congrats ... Now onto my question - I am customizing Fedora Core and I want to change the isolinux boot.msg screen to display some

Hello, I'm facing a problem that should be common but for which I don't find much info. I'm trying to smbmount some smb share served by a w2k3 server. I've no problem to mount the shares unless their name includes accented letters. I've successfully replaced the spaces in the names by \040 but replacing the accented letter by their UTF-8 and latin-1 in octal value, but

Charles Raux raised the problem of having object names with accented chars in. This is supposed to work, but depends on the machine being set to a locale that allows accented chars, and knowing correctly which they are. Windows being what it is, this is a problem. It seems that with the standard runtime crtdll.dll that rw1011 uses, Windows 9x does not know about locales, whereas NT does but

I've imported a .csv file where character strings that contained accented characters were written as HTML character entities. Is there a function that works on a vector to translate them back to accented (latin1) characters? Some examples: > grep("&", author$lname, value=TRUE) [1] "Fr&egrave;re de Montizon" "Lumi&egrave;re" [3]
