similar to: normalizePath is sometimes very slow for nonexistent UNC paths

Hi all, I saw a quite surprising result in the devel R when using the function *normalizePath*. If the input is a path to a folder, the function returns an absolute path with/without a slash at the end depending on the existence of the folder. I know both results are valid on Windows but this behavior is different than R3.6, I do not know if the change in the devel version is made on purpose.

Dear all, I'm not sure whether this is intended behaviour or a bug. The path returns from normalizePath is different when the directory doesn't exist. I have included a reproducible example. path <- tempfile() missing.dir <- normalizePath(path, winslash = "/", mustWork = FALSE) dir.create(path) existing.dir <- normalizePath(path, winslash = "/", mustWork =

Hi all, A problem with tests while building R. I'm packaging R for Sisyphus repository and package build environment, by design, doesn't have /etc/localtime file present. This causes failure with Sys.timeone during test run: [builder at localhost tests]$ ../bin/R --vanilla < reg-tests-1d.R > ## PR#17186 - Sys.timezone() on some Debian-derived platforms > (S.t <-

Hi, Back in June I posted the message below, but had no replies. I've made a little progress since then so this is to update anyone interested (!) and to ask for comments. Brief problem statement: Under Windows, some parts of R don't handle UNC paths beginning with backslashes. Specifically a) Sys.glob() fails to find some files breaking (e.g.) Rcmdr plugins

Hello, I discovered a bug or undocumented behavior in normalizePath steps to reproduce: execute normalizePath on a folder link on windows. When you are on a non-english windows box, you likely have links in place for windows' default folders, e.g. "C:\Programme" linking to "C:\Program Files" on german windows boxes. Thus executing

Hi Jiefei, the change in handling trailing path separators is not on purpose, but is a byproduct of a new implementation of normalizePath, which now handles symbolic links and normalizes case in long path names. It is not documented what happens to trailing separators, and hence portable programs should not depend on it. I don't think it is a property that should be documented/specified.

Hi Tomas, There has been an R CMD check error with xfun and r-devel on Windows for a while: https://www.r-project.org/nosvn/R.check/r-devel-windows-x86_64/xfun-00check.html Basically it means that the following would return TRUE before: normalizePath('a/b', mustWork = FALSE) == normalizePath('./a/b', mustWork = FALSE) but it became FALSE at some point in r-devel. I think

Hi, I update R from 2.10 to 2.13. Then I find soma problems when I start R. Warning infos as below: ##### Warning message: In normalizePath(c(new, .Library.site, .Library), "/") : path[1]="": No such file or directory R version 2.13.1 (2011-07-08) Copyright (C) 2011 The R Foundation for Statistical Computing ISBN 3-900051-07-0 Platform: x86_64-pc-linux-gnu (64-bit) R is

Hi, S4 method dispatch can be very slow. Would it be reasonable to cache the most recent dispatch, anticipating the next invocation will be on the same type? This would be very helpful in loops. fun0 <- function(x) sapply(x, paste, collapse="+") fun1 <- function(x) { paste <- selectMethod(paste, class(x[[1]])) sapply(x, paste,

The packages "readxl" and "haven" (and possibly others) no longer access files on shared network drives. The problem appears to be in the normalizePath() function. The file can be read from a local drive or by functions that don't call normalizePath(). The error thrown is Error: path[1]="\\Hzndhhsvf2/data/OCPH/EPI/BHSDM/Group/17.xls": The system cannot find the

Hi- I just upgraded R to 3.0.0 from 2.15.1 (which worked fine). When I started trying to install updated versions of the libraries, I saw the following error: > install.packages("lme4") Installing package into 'c:/Docume~1/melissa/R/win-library/3.0' (as 'lib' is unspecified) Warning in install.packages :

This request stems off a bug report I posted https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17757 where it was determined the current behaviour is as expected. To recap: when given a real file, normalizePath() always* returns the full absolute path. When given a non-existent file, normalizePath() returns a full path on Windows but it returns the input on other systems*. I'd argue that

I found this as well. At our institution, our home directories are on network shares that are mapped to local drives. The default, it appears, is to set the location for libraries (etc) to the network share name (//computer//share/director/a/b/user) rather than the local drive mapping (H:/). Given the issue with dir.create(), this means it's impossible to install packages (since it tries to

Hi all, I have just installed R 2.13.0 and I am experiencing problems with the terminal, but not the with the GUI interface. I am Windows 7. When running "R" or "Rterm" from a commandline I receive the following: Warning message: In normalizePath(path.expand(path), winslash, mustWork) : path[3]="C:/Programmer/R/R-2.13.0/library": Adgang n?gtet R version 2.13.0

Dear R People: I keep getting the "Error in normalizePath(path) :" while trying to obtain the necessary packages to use with the "Applied Spatial Statistics with R" book. I turned off the Firewall (from McAfee) but am still getting the same message. Does anyone have any idea on a solution please? > sessionInfo() R version 2.11.1 (2010-05-31) i386-pc-mingw32 locale: [1]

I've been getting the following warning after running 'install.packages()' recently: Warning message: insufficient OS support on this platform in: normalizePath(path) Does anyone know what this means? And does anyone know how I can get rid of the warning? I've just installed R on a fresh FC5 system so I feel I might have forgotten to install a package/library or something.

Does R have a standard function that takes two file paths (e.g., "./myDirectory/file" and "myDirectory/file") and returns TRUE if those paths refer to the same file? The paths make take different routes ("absolute" or relative paths or via different symbolic or hard links) to the same file or may use different naming conventions (Windows or DOS 8.3 on Windows). If
