similar to: setwd() permenent

I've found the following strange behaviour R (RStudio) which has been confirmed by another user in RGui. Inside a script I want to set two variables: default.wd = getwd() tmp.wd = setwd(choose.dir()) After choosing tmp.wd the value of default.wd is shown in Workspace, but getwd() is giving back the correct string of tmp.wd. Is there a workaround for the problem? I'm working on

I installed R on my Windows laptop in C:\Program Files\R\R-2.15.2 and am able to open RGUI (640bit), see packages and run commands. However, when I test the installation and run the basic tests and all the tests on the standard and recommended packages i.e.: library("tools") testInstalledBasic("both") testInstalledPackages("base", errorsAreFatal

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

Dear all, I encountered a problem on starting and using the R v 2.7.2 installation on my PC running Windows Vista and would appreciate your help. When R was first started, the Rgui returned several error messages: Error in structure(.Internal(Sys.getenv(as.character(x), as.character(unset)$ unsupported conversion Error in file.exists(name) : unsupported conversion in

Dear R-users, I used to give commands such as: > source(file="~/path/to/file.R", chdir=TRUE) but with the latest v. 2.1.0 it does not seem to work anymore. I tried to figure out what it was going on and it seems that the string for which > class(file) [1] "character" is changed to > class(file) [1] "file" "connection" when the connection is

AFAIK a script run through source() does not have any legit way to learn about it's own location. I need this to make sure that the script will find its datafiles after I move the whole directory. (The datafiles are in the same directory.) Here is a hack I invented to work around it: print(getwd()) source_pathname = get("ofile",envir = parent.frame()) source_dirname =

In my .Rprofile for Windows, I had the following functions defined to mirror a few features I miss from linux: (a) replace setwd() with a version that stashes the current directory so it can be easily restored (b) writes a short version of the current R directory to the Windows title bar: I can always see where I am, with multiple Rgui windows. (c) creates a cd() shorthand for setwd(), but

[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

Full_Name: Alex Galakhov Version: 2.1.0 OS: Linux (Debian) Submission from: (NULL) (195.19.131.68) After software upgrade source() does not work properly anymore. It completely ignores the chdir= parameter. This is because is.character(file) is always false after the assignment file<-file(file). The fix is (written by hand in diff-like syntax, hopefully, you'll understand it):

For R v2.1.1 patched and R v2.2.0 devel: Calling source(file, chdir=TRUE) with is.character(file) != TRUE, that is, with 'file' as a connection, will generate an error. Example: > file <- textConnection("cat('Hello world\n')") > source(file, chdir=TRUE) Error in source(file, chdir = TRUE) : Object "ofile" not found Of course, it does not make

Hi all, I am learning R by "doing". And this is my first post. I want to use R: 1- to fetch a DNA sequence from a databank (see bellow) and 2- store it as FASTA file. The problem: neither an error is prompted nor the fasta file is created. Testing the code (see bellow), I notice that everything works until the *"write.dna" *command - which is not creating the fasta file.

Hello, I am trying to create multiple scatter plot graphs. I have 1 independent variable (Age - weeks post conception) and 18 dependent variables ("Gene n" Expression) in one csv file. Is there a way to set up a looped function to produce 18 individual scatterplots? At the moment, I am writing the plot() function out 18 times to make the 18 graphs. My code is below and csv file is

Dear list, I have a problem with nested functions and I don't manage to get it solved. I know I should be looking in environments, and I have tried a lot, but it keeps on erroring. An easy version of the problem is as follows: innerfunction<-function() { print(paste(a, " from inner function")) print(paste(b, " from inner function")) setwd(wd) }

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/'

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

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

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 R list, I'm using R 2.15.2 with TeX Live 2009 and ESS 12.09 . I have a R project in the '/home/r/Documents/myproj/', which is my working directory (where I have the .Rnw file). Inside the document I have several "setwd()" to collect the datasets I use. After I compile from the terminal using "R CMD Sweave myproj.Rnw", I receive the error: Error in

Hi all, Is there a way to get cran R to set the working directory to be wherever the source file is? Each time I work on a project on different computers I keep having to set the working directory which is getting quite annoying. Thanks, Sachin [[alternative HTML version deleted]]
