title: converting the name of the month into date using R
body: <p>I'm struggling in cleaning a table that has multiple columns</p>
  <p>I need to covert the name of the month into a date with dummy day and year
  I have tried this function <a href="https://stackoverflow.com/questions/67345607/converting-the-name-of-the-month-into-date-using-r">here</a> but it didn't work so well.</p>
  <p>sample of table</p>
