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.

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<-sqlFetch(ch,Pollutio) > pollut Mortalit? Densit? Pollution 1 82 600 110 2 97 960

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

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 CNRS-Universit? Lumi?re Lyon 2-ENTPE email : charles.raux at let.ish-lyon.cnrs.fr http://www.ish-lyon.cnrs.fr/let

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

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

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?

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

Hello, I'm producing a 3D plot using the persp function. All my values for X, Y, and Z are decimals ranging from 0 to 1. I'd like to be able format the three axes so that the tick values are 0% 20% 40%, etc... instead of just being 0 .2 .4. Does anyone know how to do this?   Many thanks,   Steve [[alternative HTML version deleted]]

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

To whom it may concern. As I would like to analyse some array data I was keen on downloading the lumi package that depends obviously on hdrcde that is not available for r 2.12.1. I did not find instructions to solve or circumvent this problem. Installing hdrcde by hand did not work either. It was not detected by > (.packages(all.available=TRUE)) if installed in the R library. Thanks Hermann

Hi all, My name is Amy, I am a masters student in Bioinformatics at North Carolina State University. I am working on a project and I am trying to use the lumi R package for microarray data analysis. I have shown the sample code here and have questions about modifying the sample code for my own data. lumi package in R, example.lumi, the sample data has 8000 features and 4 samples I have

Hi all, I want to make a contingency table in R. I want to tabulate two variables, one as the independent and second as the dependent variable. The IV has two categories, namely, birth complications, and no birth complications. The frequency of birth complication category is fifty, and the frequency of no birth complication category is 34. The categories and frequencies of DV follows.
