For some files, file.copy() doesn't copy these files correctly. Here you will find a file (Bitmap, 769Kb) to reproduce the problem: http://www.statistik.uni-dortmund.de/leute/ligges/R/test1.bmp Using file.copy("c:/test1.bmp", "c:/test2.bmp", overwrite = TRUE) produces a second file with the size of ~1.4 Mb: http://www.statistik.uni-dortmund.de/leute/ligges/R/test2.bmp

Hi all, Could anybody please recommend some hands-on books on classification, data-mining and machine learning with R? I would like to get a very good understanding of the statistical tools that are used in these areas, while reducing the learning curve. Thank you!

Here's a fairly minimal-case example in which the saved EPS does not match the screen. The error comes when using bquote(.(i)) instead of bquote(1), as demonstrated by the two minimally different cases below. Very strange. Any clues as to why? #---------------- begin ------------------- # Version A. X axis labels have subscripts as constants. EPS is correct. windows() layout( matrix( 1:2 ,

Dear r-help, I create a package. When I installed this package (I use this command : R CMD check namepackage),I find an error: * checking whether package 'namepackage' can be installed ... ERROR Installation failed. Could you help me to find solution for this error. Best Regards [[alternative HTML version deleted]]

When I did install.packages("sqldf") on Windows and Mac OSX, it installed fine. However, when I did it on my Debian Squeeze box under R 2.14.0, it failed. I discovered that three of the dependent packages, chron, proto, and gsubfn, do not include a NAMESPACE file in their distribution tar.gz files. I contacted the developer, who told me that, for packages without a NAMESPACE file, R 2.14

Dear all mailing listers, Does Anyone have the same problem as mine when using the fast99 (extended-FAST method) to perform SA of model with norm distribution inputs? See the simple example given following. Any suggestion will be greatly appreciated. Thank you!

I applied bootpred for multinomial logistic reg. (with nnet package). I used same as theta.fit and theta.predict of R for my data. but give me error. Can I do this with response vriable;7 levels predictor variables:5 (1 classifier, 4 continuous)?   Thanks alot Azam   [[alternative HTML version deleted]]

I have drawn a 3D scatter plot : library(mnormt) library(scatterplot3d) dat = cbind(rmnorm(3, rep(0,2), diag(2)), 1:3) scatterplot3d(dat) Now I want to do 2 things : 1 : In the Z-axis (i.e. height), I want to see only numbers 1,2,3, etc NOT, 1,1.5,2,2.5............. 2. I want to add two Horizontal planes at hight z=2 and z=3. Those two planes should look like "bottom" of that 3D plot

In R-2.7.0 release as well as patched (from yesterday) under Windows XP, R crashes when typing, e.g.: repeat{ rep(1, 10000) == "?" } Note that I cannot reproduce the error in R-2.6.2 nor R-devel.

We were also able to reproduce the issue on Windows Server 2012.

Is that a method where a program that I write today would still run without changes in 10 years?

The RStudio list generally does not respond to free version users. I was hoping someone one this (R) list would be kind enough to help me.

Hi everyone,   I have got the following problem:   x1 <- rnorm(10,5,1) x2 <- runif(10,0,1) nam1 <- paste("A",1:4,sep=".") nam2 <- paste("A",6:9,sep=".") nam <- c(nam1,"A.4",nam2,"A.9") mydata <- data.frame(x1,x2) rownames(mydata) <- nam Error in `row.names<-.data.frame`(`*tmp*`, value = c("A.1",

Unfortunately, our lawyers say that they can't give legal advice in this context. My question would be, what are people looking for that the MIT or 2-clause BSD license don't provide? They're short, clear, widely accepted and very permissive. Another possibility might be to dual-license packages with both an OSI-approved license and whatever-else-you-like, e.g. 'MIT |

For the record (and as privately discussed with Brian Ripley), happens with all recent versions of R including R-devel from today: Consider a simple a.Rd file containing the lines ================== \name{a} \title{a} \value{\code{a} \code{\link[a]{a}} \pkg{a} \item{a}{a} } ================== with these lines, I get, e.g.: ================== R CMD Rdconv --type="txt" a.Rd a

dear R experts--- I am experimenting with multicore processing, so far with pretty disappointing results. Here is my simple example: A <- 100000 randvalues <- abs(rnorm(A)) minfn <- function( x, i ) { log(abs(x))+x^3+i/A+randvalues[i] } ?## an arbitrary function ARGV <- commandArgs(trailingOnly=TRUE) if (ARGV[1] == "do-onecore") { ?library(foreach) ?discard <-
