?oneway.test contains: |var.equal| a logical variable indicating whether to treat the variances in the samples as equal. If |TRUE|, then a simple F test for the equality of means in a one-way analysis of variance is preformed. If |FALSE|, an approximate method of Welch (1951) is used, which generalizes the commonly known 2-sample Welch test to the case of arbitrarily many samples. I guess

Hola! I ask here since I learnt from this list that the LaTeX package listings should be good for typesetting R code. I encountered one problem: \begin{lstlisting} X %*% V \end{lstlisting} in the output the * in %*% disappears! same with %/%, etc, the / disappears. Any ideas? Kjetil -- Kjetil Halvorsen.

I encountered something strange with read.spss (package foreign, version 0.7 with R2.0.0 and version 0.8 with R2.0.1 beta, windows XP) I made a test file test.sav with SPSS version 11.5.1 containing only one numeric variable, with a value label for one value not occuring in the file. According to ?read.spss this should result in a factor, but it results in all NA. Using the argument

I just discovered that when the VGAM package (not on CRAN) is loaded, glm() doesn't work. This is because VGAM defines a family function() which gets found by glm() in place of the family function from stats. Then VGAM:::family returns an object which doesn't have a $family component, (it has a component $vfamily). I thought namespaces should protect us from this happening? Kjetil --

I found the need of converting a matrix into a list of its columns (for use with do.call), and was surprised there was no method as.list.matrix, it could easily be a part of as.list default I wrote my.as.list.matrix <- function(mat) { if(!is.matrix(mat))stop("Argument must be a matrix") n <- NCOL(mat) res <- vector(mode="list", length=n)

Hi all, please don't ask me why I tried this but....... I have observed some odd behaviour in the time taken to read a file. I tried searching the archives without much success, but that could be me. The first time I read a (60Mb) CSV file, takes a certain amount of time. The second time takes appreciably longer and the third and subsequent times very much shorter times. See below, $

Is there any way to process the "vignette" documantation files? I have been looking at the bioconductor packages and most of them have *.Rnw files in doc directories. They look like regular TeX but have sections showing R code that seem to choke TeX.

Hi, Does anyone have a pointer to correct documantation for generating and installing a self signed ssl cert for use on httpd on a C-5 machine? The docs say to use genkey but AFAIK upstream rm'd crypto-utils from the distro and as such it is not available. I tried generating the cert on a C-4 machine using genkey and installing on the C-5 machine but I get the following error when I try to

Hello, when I work in R, I write code in a text file that I run with the "source(filename)" command. In R2.1.1 the file is read-only while the source command is executed. This was not the case in R2.0.1. Is this a bug-fix or is it possible not to have the file read-only when executed? Best regards Vidar

With rw2010dev I get a strange protect(): protection stack overflow error with a small data frame which otherwise is usable: If anybody wants to have a look I can provide an RData file with the problematic data frame.

Hello all, R2.1.1, Wk2 I am doing some two-step plotting, first using plot() to illustrate the datapoints and then using abline() to place a trend line from a fitted model into the plot. Everything works well as long as the formula of the fitted model i of the type: m1 <- lm(Dependent ~ Independent) then abline(m1) puts the proper straight line into the plot. But if I use: m2 <-

Dear all, I am trying to do a n-fold cross-validation for a regularized discrimant function analysis using rda from the package klaR.

Hi everyone, Can someone explain me how to calculate SAS type III sums of squares in R? Not that I would like to use them, I know they are problematic. I would like to know how to calculate them in order to demonstrate that strange things happen when you use them (for a course for example). I know you can use drop1(lm(), test="F") but for an lm(y~A+B+A:B), type III SSQs are only

Hi all, I'm trying to install CentOS 5 as a domU in a CentOS5 dom0 system and I use Virtual Machine Manager to do it. I've dumped all CentOS5 CDs contents in /var/www/CentOS to make a local http media source. It works fine in dom0 browser. When I arrive in "Locating installation media[*]" step I point out to http://localhost/CentOS (which is perfectly active and available)

R2.1.1 Win 2k I have a function, B, within a function, A.
