dir_ls() is equivalent to the ls command. It returns filenames as a
named fs_path character vector. The names are equivalent to the values,
which is useful for passing onto functions like purrr::map_dfr().
dir_info() is equivalent to ls -l and a shortcut for
file_info(dir_ls()).
dir_map() applies a function fun() to each entry in the path and returns
the result in a list.
dir_walk() calls fun for its side-effect and returns the input path.
dir_ls(
path = ".",
all = FALSE,
recurse = FALSE,
type = "any",
glob = NULL,
regexp = NULL,
invert = FALSE,
fail = TRUE,
...,
recursive
)
dir_map(
path = ".",
fun,
all = FALSE,
recurse = FALSE,
type = "any",
fail = TRUE
)
dir_walk(
path = ".",
fun,
all = FALSE,
recurse = FALSE,
type = "any",
fail = TRUE
)
dir_info(
path = ".",
all = FALSE,
recurse = FALSE,
type = "any",
regexp = NULL,
glob = NULL,
fail = TRUE,
...
)A character vector of one or more paths.
If TRUE hidden files are also returned.
If TRUE recurse fully, if a positive number the number of levels
to recurse.
File type(s) to return, one or more of "any", "file", "directory", "symlink", "FIFO", "socket", "character_device" or "block_device".
A wildcard aka globbing pattern (e.g. *.csv) passed on to grep() to filter paths.
A regular expression (e.g. [.]csv$) passed on to grep() to filter paths.
If TRUE return files which do not match
Should the call fail (the default) or warn if a file cannot be accessed.
Additional arguments passed to grep.
(Deprecated) If TRUE recurse fully.
A function, taking one parameter, the current path entry.
