title: Access Excel and CSV Data from OneDrive via R
body: <p>I am trying to Access some Excel and CSV files stored on both a corporate One Drive and Corporate Sharepoint via readXL - the raw data is stored there everyday and I need to import and manipulate it.
  None of the posts seems to supply and answer.
  I have tried downloading the file (get a 403 Error), using readXL to open the file and ReadCSV code.
  Every link I try seems to be can't find file.
  Any ideas?</p>
