Details
This function uses the MD5 Message-Digest Algorithm (RFC 1321) to
compute MD5 checksums of files on disk.

returns a character vector containing the string representations of the calculated MD5 checksums (represented as a string).
The names of this vector are the given filenames.
If one of the following conditions exist for a filename,
NA is returned for the filename:
- If the filename does not exist.
- If the file is not a regular file.
- If the function encounters any failures during computation.
