similar to: check does not check that package examples remove tempdir()

I think recreating tempdir() is ok in an emergency situation, but package code should not be removing tempdir() - it may contain important information.

Related to this problem - from R-devel NEWS (https://cran.r-project.org/doc/manuals/r-devel/NEWS.html): * tempdir(check = TRUE) recreates the tmpdir() if it is no longer valid (e.g. because some other process has cleaned up the ?/tmp? directory). Not sure if there's a plan to make check = TRUE the default though. /Henrik On Wed, Nov 8, 2017 at 4:43 PM, William Dunlap via R-devel

?tempdir says By default, ?tmpdir? will be the directory given by ?tempdir()?. This will be a subdirectory of the temporary directory found by the following rule. The environment variables ?TMPDIR?, ?TMP? and ?TEMP? are checked in turn and the first found which points to a writable directory is used: if none succeeds ?/tmp? is used. Unfortunately, it doesn't seem to

Hello everyone! Temp paths are used in system2() calls without shQuote() because they are assumed not to contain spaces. On Windows, GetShortPathName() is used to try to ensure that. Unfortunately, sometimes GetShortPathName() silently fails to return a 8.3 file path and gives a full path instead (8.3 file names might be disabled on newer Windows 10 installations, or there may be another

Hello R-Help I have a question about the "behind the scenes" behaviour of the Rscript -e command and particularly its interaction with Sweave and tempdir(). We are trying to deploy R as a web service to do water quality analyses and have been writing software to call Sweave via Rscript eg: cmd> Rscript -e Sweave('sweavefile.Rnw') One problem we have been having is that

Hi Mikko, I was bitten by this recently and I think some of the replies are missing the point. As I understand it, the problem consists of these elements: 1. When R starts, it creates a directory like /tmp/RtmpVIeFj4 2. Right after R starts I can create files in this directory with no error 3. After some hours or days I can no longer create files in this directory, because it has been

Hello, I run R 1.9.1 on a Windows XP machine. In the last week, I have started to get the following error message (about 85% of the time) when I attempt to start R: "Fatal error: cannot find unused tempdir name" I get this message whether I attempt to start R in interactive or batch mode. Looking at the help-manual description of tempdir didn't provide me with any obvious clues

In defense of the OP: I would have checked ?tmpdir and missed the information in the manual as well. On the help page there's ample information on the underlying processes that create the dir on multiple platforms. I think adding the last two sentences of prof. Ripley's quote as a warning to the help page, would be worth the effort. I do wonder though why you would run something that

Recent versions of Windows will remove empty directories from areas that Windows considers places for temporary files. It does not seem to matter how old they are; empty directories are found and removred c. once a day. I haven't seen any documentation on this feature but I think you can turn if off by disabling "Storage Sense" in Settings>System>Storage. This means that

Temporary files not accessed for a long time are automatically removed in some Linux distributions and probably other operating systems too, depending on system configuration. This may affect the per-session temporary directory, the path of which is returned by tempdir(). I think it would be nice if R automatically tried to recreate a missing tempdir() but this could have some performance

The main point of this discussion has been that deleting the tempdir() a fixed number of days after its creation is a problem. It should be deleted when the process that created it is done. R attempts to do this, but there are cases in which it does not so a backup is needed. Bill Dunlap TIBCO Software wdunlap tibco.com On Wed, Apr 26, 2017 at 8:46 AM, Brian G. Peterson <brian at

Hello, I am running R on XP Windows machine, and frequently I have enable to start R. I have this message: "Fatal Error: cannot find unused tempdir name". I don't know why. Thanks, in advance, for your help Sandrine Coelho

Hi, One of the functions I use needs to write to a temporary file, in the directory given by tempdir(). I want to change this from the standard one, as the file is too large for the drive. However, tempfile() doesnt seem to respect the environment variables when I change them with Sys.setenv(). In a fresh R-session: > Sys.getenv("TMP") [1]
