title: How can I create a new categories in an existing dataframe?
body: <p>I have a data set with a column name total of payments, which include payments from $100 to $1000, there are some payments that are $100.05, $102 or 104.05, which make it more difficult. If the row says for instance $97, then I want to create a column that have the categories below $100 or between 100 and 200. </p>
  
  <p>I have coded something like this; </p>
