file_temp()
returns the name which can be used as a temporary file.
file_temp(pattern = "file", tmp_dir = tempdir(), ext = "") file_temp_push(path) file_temp_pop() path_temp(...)
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 |
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.
