Functions to test for file types

Description

Functions to test for file types

Usage

is_file(path, follow = TRUE)

is_dir(path, follow = TRUE)

is_link(path)

is_file_empty(path, follow = TRUE)

Arguments

path

A character vector of one or more paths.

follow

If TRUE, symbolic links will be followed (recursively) and the results will be that of the final file rather than the link.

Value

A named logical vector, where the names give the paths. If the given object does not exist, NA is returned.

See Also

file_exists(), dir_exists() and link_exists() if you want to ensure that the path also exists.

Examples

dir_create("d")

file_create("d/file.txt")
dir_create("d/dir")
link_create(path(path_abs("d"), "file.txt"), "d/link")

paths <- dir_ls("d")
is_file(paths)
is_dir(paths)
is_link(paths)

# Cleanup
dir_delete("d")
