title: Splitting one big dataframe into multiple CSV.files
body: <p>Firstly, I have a big data.frame which has 104 rows and 12 columns, I would like to split it up to 13 rows of 8 rows each with the 12 columns.</p>
  
  <p>I am trying to make a code robust enough to not care how many rows there are but simple make a new data.frame every 8 rows. </p>
  
  <p>Also, is it possible after this point to make a code which loops through the 13 data.frames for some calculations?</p>
