All functions apart from path_real() are purely path computations, so the
files in question do not need to exist on the filesystem.
path_real(path) path_split(path) path_join(parts) path_abs(path, start = ".") path_norm(path) path_rel(path, start = ".") path_common(path) path_has_parent(path, parent)
| path | A character vector of one or more paths. |
|---|---|
| parts | A character vector or a list of character vectors, corresponding to split paths. |
| start | A starting directory to compute the path relative to. |
| parent | The parent path. |
The new path(s) in an fs_path object, which is a character vector
that also has class fs_path. Except path_split(), which returns a list
of character vectors of path components.
path_real: returns the canonical path, eliminating any symbolic
links and the special references ~, ~user, ., and .., , i.e. it
calls path_expand() (literally) and path_norm() (effectively).
path_split: splits paths into parts.
path_join: joins parts together. The inverse of path_split().
See path() to concatenate vectorized strings into a path.
path_abs: returns a normalized, absolute version of a path.
path_norm: eliminates . references and rationalizes up-level
.. references, so A/./B and A/foo/../B both become A/B, but ../B
is not changed. If one of the paths is a symbolic link, this may change the
meaning of the path, so consider using path_real() instead.
path_rel: computes the path relative to the start path,
which can be either an absolute or relative path.
path_common: finds the common parts of two (or more) paths.
path_has_parent: determine if a path has a given parent.
path_expand() for expansion of user's home directory.
