Description
Find out if a file path is a symbolic link, and if so what it is
linked to, via the system call readlink. Symbolic links are a POSIX concept, not implemented on Windows but for
most filesystems on Unix-alikes.Arguments
paths
character vector of file paths. Tilde expansion is done:
see path.expand. Value
A character vector of the same length as paths. The
entries are the path of the file linked to, "" if the path is
not a symbolic link, and NA if there is an error (e.g., the
path does not exist). On platforms without the readlink system call, all elements are
"".
