How do I say to the editor that I want to withdraw my paper from his journal?
I had submitted a paper to a journal 10 days back. When I checked recently, the status was showing "Under Review".
But just today, one of my friends found a serious flaw in one of my results! Now I need to withdraw my paper from the journal so that we both can review it and then send it again.
I also want to include my friend's name as a co-author because he helped me a lot.
Can I mail the journal editor saying I want to withdraw? It has been only a 3-4 days the status is showing "Under Review".
