similar to: write.csv(..., col.names = FALSE) (PR#13202)

Dear R developers, It would be great if you could implement the two minor code changes suggested below, which would help processing large objects in R. Jens Oehlschl?gel # Wish no. 1: let [.AsIs return the class AFTER subsetting, not the class of the original object # Wish no. 2: adjust write.csv and write.csv2 for multiple calls in chunked writing # Rationale no. 1: a couple of packages

Hi, I am writing a function that writes to a csv file for every call. However, for the subsequent calls, I want to append the data to the existing csv file without appending the column names again. I tried searching in the previous posts, but I am stuck with different errors. Here is what I am doing (dataF is a data-frame):- outputFilePath <- paste(getwd(), "/",

The write.csv() function is currently implemented as function (..., col.names=NA, sep=",", qmethod="double") { write.table(..., col.names=NA, sep=",", qmethod="double") } Surely, it should be function (..., col.names=NA, sep=",", qmethod="double") { write.table(..., col.names=col.names, sep=sep,

Hello all, I had some trouble recently with write.csv because I couldn't change one of the default options. A quick view of the code showed that the function was not defined in the most optimal way. Currently, write.csv <- function (..., col.names = NA, sep = ",", qmethod = "double") write.table(..., col.names = NA, sep = ",", qmethod = "double")

Attempting to write a vector to a csv file without column headers does not work as documented. The col.names=false feature on the write.table command does however work and it can thus be coerced

Dear all, I have problems to compile a DLL for Windows XP with R version 2.5.1 (2007-06-27).

Dear all, I would like to inquire, if it is a desired feature that the combination with rbind() of two data frames with factors columns does not sort the factors levels of the combined data frame. > str(rbind(data.frame(a = factor(c(4, 3))), data.frame(a = factor(c(2, 1))))) 'data.frame': 4 obs. of 1 variable: $ a: Factor w/ 4 levels

Dear all, I am trying to install packages with the new R 2.0.0. However for several packages, like MASS, lattice or R2HTML, I get an error like: > library(lattice) Error in library(lattice) : 'lattice' is not a valid package -- installed < 2.0.0? > However, I have just downloaded the latest versions from CRAN. As far as lattice is concerned, it seems that the Windows binary is

Thanks to all who have responded. My concern was to be able to write a csv file that can have line feeds in string columns chr(10). Why? Excel allows line feeds chr(10) within cells and line breaks chr(13)+chr(10) at line ending, but the windows version of R automatically replaces \n by \r\n in writing and \r\n by \n in reading (text mode). The clues for a solution came from Brian Ripley and

Hi there My script at each iteration produces a .dat file which I save in a directory with write.table. Then I need to read each line of this file and create a directory for each line and put elements of that row in that directory. I do it with the following script which I have inserted somewhere between my outer iteration loop, it works fine for the first iteration, but the problem is that it
