title: Self iteration in R
body: <p>I have a column in excel (created a sample data below) called Name that is in the format below <br></p>
  
  <p>Name(Column Header) <br>
  A,Y - B,X<br>
  C,Q - W,R<br>
  and list goes on and<br>
  B,X - A,Y <br>
  W,R - C,Q <br>
  T,U - K,M<br></p>
  
  <p>each row has corresponding 20 other columns. I need to remove all the rows that are  present in Name column in reverse format. Such as "B,X - A,Y" and "W,R - C,Q" and all its corresponding column values but the rows "A,Y - B,X" and "C,Q - W,R" should not be deleted.</p>
