file_temp() returns the name which can be used as a temporary file.
Usage
file_temp(pattern = "file", tmp_dir = tempdir(), ext = "")
file_temp_push(path)
file_temp_pop()
path_temp(...)Arguments
- pattern
A character vector with the non-random portion of the name.
- tmp_dir
The directory the file will be created in.
- ext
The file extension of the temporary file.
- path
A character vector of one or more paths.
- ...
Additional paths appended to the temporary directory by
path().
Details
file_temp_push() can be used to supply deterministic entries in the
temporary file stack. This can be useful for reproducibility in like example
documentation and vignettes.
file_temp_pop() can be used to explicitly remove an entry from the
internal stack, however generally this is done instead by calling
file_temp().
path_temp() constructs a path within the session temporary directory.
Examples
path_temp()
#> /tmp/Rtmp9jM0mE
path_temp("does-not-exist")
#> /tmp/Rtmp9jM0mE/does-not-exist
file_temp()
#> /tmp/filedd461c46df20
file_temp(ext = "png")
#> /tmp/Rtmp9jM0mE/file273e8f2966e.png
file_temp("image", ext = "png")
#> /tmp/Rtmp9jM0mE/image273e1b5e52dd.png
# You can make the temp file paths deterministic
