Is there a function in core R that takes 2 strings and returns TRUE if they refer to the same file? (If either does not refer to a file, I think it would be fine if it returned FALSE.)
No, but equality for normalizePath() works well enough on most OSes (Unix-alikes do follow links, although if you have a file system mounted in multiple places I have no idea how well it copes).
Compariing inode/device numbers on Unix-like systems and the output of normalizePath on Windows would probably do it. Comparing files on non-native file systems can mess things up so perhaps we should not promise much.
