similar to: assignInNamespace to create a setwd() replacement: how to use unlockBinding()?

[Env: Win XP, R 2.14.2, R 2.15.0] I have a replacement function for setwd() in my .Rprofile which displays the current R path in the R window title. It no longer works in R 2.15.x, giving the error below. Worse, the error prevents the rest of my .Rprofile script from completing. Is there some way to rescue this, i.e., preserve this behavior in R 2.15? If not, how can I modify my script so it

In my .Rprofile I have the following functions which display the current directory in the main R window title bar, and modify base::setwd() to keep this up to date. I like this because I can always tell where I am in the file system. cd <- function(dir) { base::setwd(dir) utils::setWindowTitle( short.path(base::getwd()) ) } short.path <- function(dir, len=2) { np

Hello, assignInNamespace refuses to assign an object to a name that is not already used in the namespace. Something like this would make it possible: --- src/library/utils/R/objects.R (revision 56024) +++ src/library/utils/R/objects.R (working copy) @@ -252,8 +252,9 @@ stop("environment specified is not a package") ns <- asNamespace(substring(nm, 9L))

A coworker got tired of having to type 'yes' or 'no' after quitting R: he never wanted to save the R workspace when quitting. So he added assignInNamespace lines to his .Rprofile file to replace base::q with one that, by default, called the original with save="no".. utils::assignInNamespace(".qOrig", base::q, "base")

I am trying to get a function written in R that calls a cascade of functions from the graphics package, and I want to eventually call replacements to functions in the graphics package instead of the originals. Specifically, I have a function that calls qqnorm in stats, which calls qqnorm.default in stats, which calls plot in graphics, which calls plot.default and plot.new, and I want my own

I started my laptop, opened a shell and get this error message: R : Copyright 2005, The R Foundation for Statistical Computing Version 2.2.1 (2005-12-20 r36812) ISBN 3-900051-07-0 lines deleted Error in fun(...) : couldn't find function "assignInNamespace" Error: .onLoad failed in 'loadNamespace' for 'Matrix' Fatal error: unable to restore saved data in .RData

The problem is not specific to redefining the q function, but to the interaction of assignInNamespace and setGeneric. The latter requires, roughtly, that the environment of the function being replaced by an S4 generic is (or is the descendent of) the environment in which it lives. E.g., the following demonstrates the problem % R --quiet --vanilla > assignInNamespace("plot",

Hi Bill, Ideally, your coworker would just make an alias (or shortcut or whatever) for R that passed --no-save to R. I'll try to look into this though.

I hope others may find this useful. I use R in many different directories. By adding the following line to the .Rprofile file: utils:::setWindowTitle(paste("-",getwd())) the titlebar of each R instance shows the directory from which it was started. I have tested this with rterm.exe and rgui.exe under Windows and with RECENT versions of R only. ----- For changing directories

Hey, two questions regarding setwd and list.files: I try to use the function list.files: >datapath<-'/nfs/home/m/cremer/gaw/data/traws_chrs' >fl<-list.files(datapath, pattern="\\.tped") but I get the following error message: Warning message: In list.files(datapath, pattern = "\\.tped") : list.files: '/nfs/home/m/cremer/gaw/data/traws_chrs/'

¡Hola! ¿Alguien sabe si existe una función en R que devuelve el nombre del área de trabajo (workspace) en uso si éste ha sido guardado anteriormente? Con getwd() R me devuelve la carpeta de trabajo, pero si en ésta tengo varios áreas de trabajo guardados, p.e. a.RData y b.RData, ¿cómo podría saber en cuál estoy trabajando si por un despiste no me acordara cuál he abierto anteriormente (sin tener

Hello I think there is a conflict between setwd() and \SweaveOpts{prefix.string=}. In the same document, those both command get Sweave confuse the files and directories. See: say my .Rnw document is in File1 If one inserts some setwd() for another file: -setwd(File2) then the command \SweaveOpts{prefix.string=graphics/Rplots} will search the "graphics" folder in File2 because of

Hello, I am using R for Windows and I receive error messages when trying to change my working directory: > setwd('C:\BACC_R') Error in setwd(dir) : cannot change working directory I would really appreciate your help, Joan Serra

Dear friends - windows R 3.3.3 - sorry to ask a simple question - but I cannot make setwd work properly in scripts In the example below I have made a directory in C (firstdir) and a directory in that (secdir) and the intention is to change directory to the second from the first - it works when I put the entire path but not the tilde - what am I missing? I was around rwf 2.14 as per the help

Below is a patch for setwd() to show path in error message. Current it just gives error messages such as: Error in setwd(libdir) : cannot change working directory with the patch it should (read untested) give: Error in setwd(libdir) : cannot change working directory to 'path/that/fails/' PATCH: % diff -u util.c "util,patch.c" --- util.c 2012-12-16 13:13:05.002249900

Hello when I close and reopen R it gives back a different wd than what I used in setwd. how can I get it to permenently use dirname in setwd("dirname") and not the other name it keeps defaulting to? I am using W2K and ESS thanks

Hi Guys, I am new to R and just trying to write a small script to automate a couple commands. But I run into the setwd(): cannot change working directory. I googled a little bit and tried all fixes/suggestions with no success. Basically I have a script that works from inside a directory with my data (/home/sean/Rtest/Data01). Now I want to modify the script to make it run from the upper directory

Dear all, my R files (and the .csv files as well) are saved somewhere pretty deep down my hard disk. i have to chage to working directory therefore everytime i run R (i run it on powerPC mac), which is disgusting. using the setwd command at the beginning of an R script doesnt really help because i have to find this file first by hand. I am looking for possibility to run setwd during the
