search for: tempfile

The other day I was working on an example which used tempfile() to create file for use by the graphics device. And while I love tempfile()---as it is portable and clever and the files get cleaned by R and all that---I noticed one missing feature I would like to see: beside a starting name pattern, and an optional directory, an 'file extension' argumen...

G'day all, The documentation for tempfile states : "The names are very likely to be unique among calls to tempfile in an R session and across simultaneous R sessions. The filenames are guaranteed not to be currently in use." My problem I think relates to the second part of the sentence, which is the guarantee... and it is being...

Hi all, Yesterday, I had some problems reading JPG files in my tests. Turns out the problem was that Windows Ruby doesn't set it's Tempfile to work in binary mode. Since I deploy on Linux, that has never been a big problem, but now I'm working on some software that works with binary files exclusively. Anyway, I am making this fix available as a Rails plugin. The details can be found here: http://blog.teksol.info/articles/2006/12...

...opular) "Systemd": $ mkdir /tmp/somedir $ touch -d "12 days ago" /tmp/somedir/ $ cd /tmp/somedir/ $ sudo systemd-tmpfiles --clean $ ls /tmp/somedir/ ls: cannot access '/tmp/somedir/': No such file or directory I would advocate just changing 'tempfile()' so that it recreates the directory where the file is (the "dirname") before returning the file path. This would have fixed the issue I ran into. Changing 'tempdir()' to recreate the directory is another option. Thanks, Frederick

Hi I have a linux box which has CentOS running in it. I logged into the box using root and wrote a script in the /home/proc_threads directory. saved the file and quit. I changed the file permissions such that any user could execute it using the "chmod 777 filename" command. When i log out and log in as a non-root user i was not able to execute the script though. Could some one

...mistakenly use file.copy() with a directory for the 'from' argument and a non-directory for the 'to' and overwrite=TRUE, file.copy returns FALSE, meaning it could not do the copying. However, it also replaces the 'to' file with a zero-length file. dir.create( fromDir <- tempfile() ) cat(file = toFile <- tempfile(), "existing file\n") readLines(toFile) #[1] "existing file" file.copy(fromDir, toFile, recursive=FALSE, overwrite=TRUE) #[1] FALSE readLines(toFile) #character(0) or, with recursive=TRUE, dir.create( fromDir <- tempfile() ) cat(file = t...

Dear List: I am encountering an error that I can't resolve. I'm looping through rows of a dataframe to generate individual tex files using Sweave. At random points along the way, I encounter the following error Error in file() : cannot find unused tempfile name At which point Sweave halts. There isn't a logical pattern that I can identify in terms of why the program stops at certain points. It just seems to be random as far as I can tell. I've searched the archives and of course Sweave FAQs but haven't found much that sheds light on what...

...he solution is more of a cheap hack that works for now. To provide a little background, I am looping through a dataframe and creating Sweave documents using data from each row in the dataframe. It appears that this technique is not scalable to large dataframes without making some changes to the way tempfiles are handled. In the background, R generates tempfiles in a directory using a sequential number. In my case, the numbers ranged from Rf1 to Rf32767. The next in line would of course be Rf32768. This number happens to coincide with 2^15-1, which my programmer colleagues tell me is the maximum posit...

Currently a power failure or other hard crash can cause lld leave a temporary file around. The same is true for other llvm tools. As an example, put a breakpoint in Writer.cpp:236 ("writeBuildId()") and restart the run a few times. You will get t.tmp43a735a t.tmp4deeabb t.tmp9bacdd3 t.tmpe4115c4 t.tmpeb01fff The same would happen if there was a fatal error between the
