Hello, I just tried the rw0640 version for Windows95. If I type link.html.help() a 1: appears. Does anyone knows what to type in after that, it seems that some input is required?

Ladies and gentlemen, this email is directed to all German-speaking members of the r-help list. We from the chair of statistics and quantitative methods on the Catholic University of Eichst?tt-Ingolstadt, Germany, are searching for a new colleague. You will find the corresponding job offer in the attachment. If you are interested, please don?t shy and send us your application on the

Dear list, I came up with a two functions that flatten arbitrary deeply nested lists (as long as they're named; not tested for unnamed) and environments (see attachment; 'flatten_examples.txt' contains some examples). The paradigm is somewhat similar to that implemented in 'unlist()', yet extends it. I would have very much liked to build upon the superfast functionality

Dear List, I’m doing my first baby steps towards developing own R Packages and ran into the following problem: R CMD check mypackage works fine (no errors, no warnings) R CMD build mypackage works fine (no errors, no warnings) R CMD INSTALL –library=”C:\R\R-2.11.1\library” “something\mypackage\mypackage_1.0.tar.gz” works fine (no errors, no warnings) However, when I try loading the

Dear list, I hope this is the right place to post a feature request. If there's exists a more formal channel (e.g. as for bug reports), I'd appreciate a pointer. I work a lot with named nested lists with arbitrary degrees of "nestedness". In order to retrieve the names and/or values of "bottom layer/bottom tier", I love the functionality of 'unlist()', or

Dear list, today I stumbled across the function ?nsl()? for the first time in order to perform a hostname lookup. According to the R Reference Index (Version 2.9.1, page 1522), the function should be part of the "utils" package. However, I cannot find it in the utils package of my installation(s). I've tried the R-versions 2.8.1, 2.9.0 and 2.9.1. I'd be very thankful if

Dear List, I am not really familiar with any other language than R, but I?ve heard that in other languages there is something called ?self referencing?. Here?s what I?m trying to get an answer for: Suppose there is a function that takes as its input a value of a slot of an S4 object. The function itself is stored in another slot of the SAME S4 object. Is it then possible to have the function

I apologize for accidentally omitting some of the answers I got; here they are: ************** I use R regularly in my research in the pharmaceutical industry. I have used it for projects ranging from sample size and power curve estimation, analysis of laboratory data with mixed effects models, to analysis of mass spectrometry data. I have helped biologists here install and use it in limited

Dear list, I was wondering if you could help me out in clarifying something: Is it possible to use class "ANY" in slots/fields of formal classes if you a) do not want to restrict valid classes of that field and b) if you are making explicit use of class inheritance? It seems to work in simple scenarios but produces errors when class inheritance comes into play. So I was

Hi, How could I use R to check Durbin Watson Test Bound? Best, Rebecca

Should "dwtest" and "durbin.watson" be giving me the same DW statistic and p-value for these two fits? library(lmtest) library(car) X <- c(4.8509E-1,8.2667E-2,6.4010E-2,5.1188E-2,3.4492E-2,2.1660E-2, 3.2242E-3,1.8285E-3) Y <- c(2720,1150,1010,790,482,358,78,35) W <- 1/Y^2 fit <- lm(Y ~ X - 1) dwtest(fit,alternative="two.sided")

Dear R People: Do any of the linear model or regression function calculate the Durbin-Watson test statistic for serial correlation, please? I found the hat matrix, studentized residuals, and so on, but no D-W. Thanks so much! Sincerely, Erin M.

Hi, I have two time series, y and x. Diff(y) and Diff(x) both show no autocorrelation. But durbin.watson(lm(Diff(y)~lag(Diff(x),k=-4)) gives a DW value of zero. How come the residule is autocorrelated while Diff(y) and Diff(x) are not? Does anyone know if in my case a DW of zero indicates serial correlation, or is it telling me that the DW statistics is not the appropriate statistics to use here?

Sir,   I am unable to get the source code for Durbin-Watson test, as I want to calculate the p-value for Durbin Watson statistic using interpolation method. I sent this mail to r-help, but it was rejected, please suggest me some way. I will be highly greatful to you. Thanks in advance Ramesh [[alternative HTML version deleted]]

Hello! I have a data frame mysample (sorry for a long way of creating it below - but I need it in this form, and it works). I regress Y onto X1 through X11 - first without weights, then with weights: regtest1<-lm(Y~., data=mysample[-13])) regtest2<-lm(Y~., data=mysample[-13]),weights=mysample$weight) summary(regtest1) summary(regtest2) Then I calculate Durbin-Watson for both regressions

Hi, I ran an experiment with 3 factors, 2 levels and 200 replications and as I want to test for residuals independence, I used Durbin-Watson in R. I found two functions (durbin.watson and dwtest) and while both are giving the same rho, the p-values are greatly differ: > durbin.watson(mod1) lag Autocorrelation D-W Statistic p-value 1 -0.04431012 2.088610 0.012 Alternative

Dear R developers: When using R.0.99a (Version 0.99.0 Patched (February 9, 2000), source compiled with gcc under SuSE 6.2) on a PIII 500Mhz Machine under SuSE 6.2 Linux I found the following bug: x <- matrix(0,10,0) rbind(x,2) causes an R-crash with the message "Gleitkomma-Ausnahme" (floating point exception) which is probably due to the non-applicability of the recyling
