Create files, directories, or links

These functions ensure that path exists; if it already exists it will be left unchanged. That means that compared to file.create(), file_create() will not truncate an existing file, and compared to dir.create(), dir_create() will silently ignore existing directories.

file_create(path, ..., mode = "u=rw,go=r")

dir_create(path, ..., mode = "u=rwx,go=rx", recurse = TRUE, recursive)

link_create(path, new_path, symbolic = TRUE)

Arguments

path	A character vector of one or more paths.
...	Additional arguments passed to path()
mode	If file/directory is created, what mode should it have? Links do not have mode; they inherit the mode of the file they link to.
recurse	should intermediate directories be created if they do not exist?
recursive	(Deprecated) If TRUE recurse fully.
new_path	The path where the link should be created.
symbolic	Boolean value determining if the link should be a symbolic (the default) or hard link.

Value

The path to the created object (invisibly).

Examples

.old_wd <- setwd(tempdir())
file_create("foo")
is_file("foo")
#>  foo 
#> TRUE 
# dir_create applied to the same path will fail
try(dir_create("foo"))
#> Error : [EEXIST] Failed to make directory 'foo': file already exists

dir_create("bar")
is_dir("bar")
#>  bar 
#> TRUE 
# file_create applied to the same path will fail
try(file_create("bar"))
#> Error : [EISDIR] Failed to open 'bar': illegal operation on a directory

# Cleanup
file_delete("foo")
dir_delete("bar")
setwd(.old_wd)
