title: Extracting value and finding the minimum without merging
body: <p>I'm trying to extract a subtext and get the minimum value from a list of a list in R. My initial tsv looks like this (this is a smaller version): </p>
  
  <pre><code>cases                                              counts
  "S35718:10.63,S35585:6.75,S35708:7.28,S36617:12.23" "6.75,7.28,10.63,12.23,6.17,4.09,3.95,5.00"
  "S35718:10.63"                                      "10.63"
  
  </code></pre>
  
  <p>And I am trying to extract the numbers after the colon and find the minimum, then I wanted to see how many in the counts column are greater than the minimum. </p>
  
  <p>For instance my ideal output would be: </p>
  
  <pre><code>min: 6.75
  greater than 6.75 in counts column: 4
  </code></pre>
  
  <p>Within this .tsv, there are approximately 100,000 lines. I've tried using gsub, but it ends up merging all the numbers such as the example below:</p>
  
  <pre><code>test &lt;- gsub(".*:", "",outlier$cases)
  [1]"10.63" "6.75" "7.28" "12.23" "10.63" ... all the other subsequent values
  </code></pre>
  
  <p>I would appreciate any help on this. I'm a bit of a beginner with R but would love to improve further. Thank you so much!</p>
