Answer 1

See help ?unlink:

0 for success, 1 for failure, invisibly. Not deleting a non-existent file is not a failure, nor is being unable to delete a directory if recursive = FALSE. However, missing values in x are regarded as failures.

In the case where there is a folder foo the unlink call without recursive=TRUE will return 1.

Note that actually the behavior is more like rm -f, which means that unlinking a non-existent file will return 0.
