Functions to test for file types

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

.old_wd <- setwd(tempdir())
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)
#>      d/dir d/file.txt     d/link 
#>      FALSE       TRUE       TRUE 
is_dir(paths)
#>      d/dir d/file.txt     d/link 
#>       TRUE      FALSE      FALSE 
is_link(paths)
#>      d/dir d/file.txt     d/link 
#>      FALSE      FALSE       TRUE 

# Cleanup
dir_delete("d")
setwd(.old_wd)
