You can get it at: http://www.bfro.uni-lj.si/MR/ggorjan/programs/shell/Sweave.sh No warranty, however don't hesitate to contact me if you find an error or have a patch! -- Lep pozdrav / With regards, Gregor GORJANC --------------------------------------------------------------- University of

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

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

Hello! I was reading R-intro and I have some suggestions: R-intro.html#A-sample-session rm(fm, fm1, lrf, x, dummy) suggestion rm(fm, fm1, lrf, x, y, w, dummy) The next section will look at data from the classical experiment of Michaelson and Morley to measure the speed of light. file.show("morley.tab") mm <- read.table("morley.tab") suggestion mm <- data(morley)

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

Hello! I have a continous distribution and would like to get mode (the most frequent value in distribution). I easily found mean, median and other basic thing but not mode function. Can anyone help? I know there my might be problems with multiple modes, but still I think that there should be a mode function in R. Please send mail to R-help list and me, so I can get response faster. Thank

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

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

Hello! I am trying to get specific fields from an XML document and I am totally puzzled.

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,

Hello to Rusers! I am puzzled with R and I really do not know where to look in for my problem. I am moving from SAS and I have difficulties in translating SAS to R world. I hope I will get some hints or pointers so I can study from there on. I would like to do something like this. In SAS I can write a macro as example bellow, which is afcourse a silly one but shows what I don't know how

Hello! I am producing a set of images and I would like them to be sorted by names I give. I was able to produce my names and add integer to them. That is easy. But my problem lies in sort of file from this process: figure_10.png figure_11.png figure_12.png ... figure_1.png figure_20.png ... So I would like to convert integers to something like 01 if upper limit for this conert is 10 or 001

Hello! Is it possible to set na.rm=TRUE in a global way? I'am constantly forgeting on this when performing analyses. I agree that one should be carefull with this when developing some code, but not necesarilly so in data analysis.

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. Is

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 <-

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.
