Test for argument in ...
Hello! Say I have a function foo1, which has argument ... to pass various arguments to foo2 i.e. foo1 <- function(x, ...) { foo2(x, ...) } Say that foo2 accepts argument arg1 and I would like to do the following: - if foo1 is called as foo1(x) then I would like to assign some value to arg1 inside foo1 before calling foo2 arg1 <- "some value" foo2(x, arg1=arg1) - if foo1 is

Random seed problem in MCMC coupling of chains
Hello! I am performing coupling of chains in MCMC and I need the same value of seed for two chains. I will show demo of what I want: R code, which might show my example is: niter <- 3 nchain <- 2 tmpSeed <- 123 for (i in 1:niter) { # iterations for (j in 1:nchain) { # chains set.seed(tmpSeed) a <- runif(1) cat("iter:", i, "chain:", j,

Fitdistr and MLE for parameter lambda of Poisson distribution
Hello! I would like to get MLE for parameter lambda of Poisson distribution. I can use fitdistr() for this. After looking a bit into the code of this function I can see that value for lambda and its standard error is estimated via estimate <- mean(x) sds <- sqrt(estimate/n) Is this MLE? With my poor math/stat knowledge I thought that MLE for Poisson parameter is (in mixture of LaTeX

A concrete type I/III Sum of square problem
Hi R-help members, I have read a lot in the Archive about the "Type I" vs "Type III" sum of square. I think I have read confusing post so I want to have a clear idea of the problem. Here is an example. I have 3 groups of subjects of unequal sample size (G1 (n=7), G2 (n=7), G3 (n=4)). for Each subject I have 4 measures corresponding to the crossing of 2 factor (A & B)

Making R talk to Win/OpenBUGS in Linux (again)
I'm back! I've just learned that, on a fully updated Fedora Core Linux5 sytem, the working solution to access Winbugs under wine via the R package "rbugs" no longer works. Here was my last post on this topic (with the formerly working solution) from January. http://finzi.psych.upenn.edu/R/Rhelp02a/archive/68497.html Currently, what happens is that WinBUGS starts up, but just

levels for list and data.frame
Hello! Does R core find the following pacth usefull - I created methods for levels for list and data.frame, which can be usefull to get a list of levels for entries in a list or columns in a data.frame. Patch is attached and shown bellow example # Example > tmp <- list() > tmp$a <- factor(letters[1:10]) > tmp$b <- factor(letters[5:14]) > tmp$c <- 1:10 > tmp1 <-

Constrain coefs. in linear model to sum to 0
Hello! I would like to use constrain to sum coeficients of a factor to 0 instead of classical corner contraint i.e. I would like to fit a model like lm(y ~ 1 + effectA + effectB) and say get parameters intercept effectA_1 effectA_2 effectB_1 effectB_2 effectB_3 where effectA_1 represents deviation of level A_1 from intercept and sum(effectA_1, effectA_2) = 0 and the same for factor B.

F90
Hello! Has anyone successfully compiled F90 sources in R-package? I found the same question on r-devel list from 2002 and I wonder if there is any progress. I heard that g95 and gfortran can be usable. And one more thing. I have a program written in F90 and lets suppose that compiler is not a problem. I've read manual 'Writing R Extensions' and successfully loaded one F77 subroutine

Sweave and \input or \include LaTeX commands
Hello! I was just wondering if Sweave can work with \input or \include LaTeX commands. So, is it aware of such a possible hierarchy in documents. I would test that, but I don't have such a report available at the moment. I thought of that when I was writting shell script for Sweave from command line and I have solved that part there. -- Lep pozdrav / With regards, Gregor GORJANC

How long is winepath available?
Hello! Can someone provide me an estimate or relevant source of information on how long is command winepath available or from wich version of wine? I would need this as I work on some R[1] package R2WinBUGS[2] that calls a Windows program WinBUGS[3] and that program needs windows paths. Currently winepath or parsing of .wine/config is used and I wonder if I can remove fiddling with .wine/.config.

Upgrading R
Hello! New version of R has came out and I would like to thank to all developers on this matter. So I should probably upgrade. Fine and no problem. For windows I just grab the latest precompiled binnaries and install them. Then I see a report on a bug, which is or will be fixed in pacthed version. So I need to get binnaries from patched build and install them, right? How often do you people

Current state of support for BUGS access for Linux users?
Greetings: I'm going to encourage some students to try Bayesian ideas for hierarchical models. I want to run the WinBUGS and R examples in Tony Lancaster's An Introduction to Modern Bayesian Econometrics. That features MS Windows and "bugs" from R2WinBUGS. Today, I want to ask how people are doing this in Linux? I have found a plethora of possibilities, some of which are not
