.TRUE
then an error is given if the result
cannot be determined; if NA
then a warning.path.expand
) is first done on
paths
. Where the Unix-alike platform supports it attempts to turn paths into
absolute paths in their canonical form (no ./, ../ nor
symbolic links). It relies on the POSIX system function
realpath
: if the platform does not have that (we know of no
current example) then the result will be an absolute path but might
not be canonical. Even where realpath
is used the canonical
path need not be unique, for example via hard links or
multiple mounts.
On Windows it converts relative paths to absolute paths, converts
short names for path elements to long names and ensures the separator
is that specified by winslash
. It will match paths
case-insensitively and return the canonical case.
UTF-8-encoded paths not valid in the current locale can be used.
mustWork = FALSE
is useful for expressing paths for use in
messages.
