file_copy() copies files.
link_copy() creates a new link pointing to the same location as the previous link.
dir_copy() copies the directory recursively at the new location.
Usage
file_copy(path, new_path, overwrite = FALSE)
dir_copy(path, new_path, overwrite = FALSE)
link_copy(path, new_path, overwrite = FALSE)Arguments
- path
A character vector of one or more paths.
- new_path
A character vector of paths to the new locations.
- overwrite
Overwrite files if they exist. If this is
FALSEand the file exists an error will be thrown.
Details
The behavior of dir_copy() differs slightly than that of file.copy() when
overwrite = TRUE. The directory will always be copied to new_path, even
if the name differs from the basename of path.
Examples
.old_wd <- setwd(tempdir())
file_create("foo")
file_copy("foo", "bar")
try(file_copy("foo", "bar"))
#> Error : [EEXIST] Failed to copy 'foo' to 'bar': file already exists
file_copy("foo", "bar", overwrite = TRUE)
file_delete(c("foo", "bar"))
dir_create("foo")
# Create a directory and put a few files in it
files <- file_create(c("foo/bar", "foo/baz"))
file_exists(files)
#> foo/bar foo/baz
#> TRUE TRUE
# Copy the directory
dir_copy("foo", "foo2")
file_exists(path("foo2", path_file(files)))
#> foo2/bar foo2/baz
#> TRUE TRUE
# Create a link to the directory
link_create(path_abs("foo"), "loo")
link_path("loo")
#> /tmp/RtmpHFCmia/foo
link_copy("loo", "loo2")
link_path("loo2")
#> /tmp/RtmpHFCmia/foo
# Cleanup
dir_delete(c("foo", "foo2"))
link_delete(c("loo", "loo2"))
setwd(.old_wd)
