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
""
.
