title: How to slice dataframe into multiple dataframes in R
body: <p>I have the following problem: I have a big dataframe with this format:</p>
  <p><a href="https://i.stack.imgur.com/pRFBh.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pRFBh.png" alt="enter image description here" /></a></p>
  <p>Each of these measurements represents a whole cell with the name that contains the &quot;:&quot; regular expression, the ones that follow are area measurements of points inside a cell with their respective areas.</p>
  <p>I would like to subset this into multiple dataframes containing just the part that ranges from the name with &quot;:&quot; to the next one. In this example it would be from row 1 to 14 and then from 15 to the next before the regular expression with &quot;:&quot;.</p>
