title: How to format numbers as percentage values but to still be able to treat ir numercially?
body: <p>I want to know if it's possible to display values on a table as percentages but still be able to do arithmetic operations with them.</p>
  
  <p>I have tried using <code>percent()</code> from <code>scales</code> package, but it seems like it transforms the values from numeric to character. I have tried to convert them back using <code>as.numeric()</code>, but it will not work either.</p>
  
  <p>Any solutions? Thank you.</p>
