R 笔记(2)

incomplete final line found by...

The message indicates that the last line of the file doesn't end with an End Of Line (EOL) character (linefeed (\n) or carriage return+linefeed (\r\n)). The original intention of this message was to warn you that the file may be incomplete; most datafiles have an EOL character as the very last character in the file.

The remedy is simple:

1. Open the file
2. Navigate to the very last line of the file
3. Place the cursor the end of that line
4. Press return
5. Save the file
