I am trying to save an R data.frame as an Excel sheet. I do NOT want the column names saved into row 1. I set colnames=F. However, it still seems that the colnames are saved into row 1. Is this a bug? Or am I coding incorrectly and.or misunderstanding this feature? #example code: sheet = "c:/test2.xls" temp=data.frame(matrix(data=NA,nrow=10,ncol=15)) temp[1,1] =

Dear ExpRts, I would like to perform a function with two arguments over the rows of two matrices. There are a couple of *applys (including mApply in Hmisc) but I haven't found out how to do it straightforward. Applying to row indices works, but looks like a poor hack to me: sens <- function(test, gold...

Dear expRts, I just realized that the "..." argument in a function cannot be used without taking precautions sometimes. The following behaviour is what I stumbled upon: > myrepl <- function(length, fun, ...) { + replicate(length, fun(...))} > myrepl(20, sample, 1:5) [1] 0 0 0 0 0 0 0 0 0...

Dear expRts, when I try to build a package by myself, the process fails writing the following messages to 00install.out: * Installing *source* package 'dynalc' ... ** libs WARNING: no source files found chmod: Zugriff auf ?/home/hannes/texte/forschung/clot/programme/dynalc.Rcheck/dynalc/libs/*? nicht...

I'm now doubting if I've made this statement or not, so here it is: newmge-shut is *not* ready for production usage! I've lately found some bugs during the MGE PSP 3.0.4/3.0.5/3.0.6 updates. So for the moment, prefer to keep using mge-shut. 2007/10/25, R?zsa G?bor <mailer.tovis at freemail.hu>: > newmge-shut ??? > Shutdown, switch of ups does not work. Using command >

Dear lists, I'm in my process of learning of writing a function. I tried to write a simple functions of a matrix and a vector. Here are the codes: mm<-function(m,n){ #matrix function w<-matrix(nrow=m, ncol=n) for(i in 1:m){ for(j in 1:n){ w[i,j]=i+j } } return(w[i,j]) } v<-function(n){ #function of a vector y=vector(length=n)
