What do you mean by "different meaning"? How are the command line tools [1] relevant when R is using the C function 'readlink'? http://pubs.opengroup.org/onlinepubs/9699919799/functions/readlink.html https://www.freebsd.org/cgi/man.cgi?query=readlink&sektion=2 http://man7.org/linux/man-pages/man2/readlink.2.html -- Mikko Korpela Aalto University School of Science Department of Computer Science ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
