title: Delete empty csv files in directory - R
body: <p><br>
  I have many csv files in a folder (1.csv,2.csv....,20.csv) but a few of them are empty (5.csv,8.csv). The empty files even contain a size around 4 bytes and are not size 0. 
  <br>
  I need to delete them in the directory and I want to achieve this in R. Is this possible? Appreciate any help!</p>
