I asked a question on SO (R independent columns in matrix) several months ago and I don't think it is a good question. It is less about programming and more the understanding of the mathematics of the problem.
I don't think the question adds any value and should be deleted.
Since it has answers I cannot delete it myself. I flagged it and the flag was deemed "helpful". Nevertheless, it was not closed and I voted to close the question. Now it has one close vote. How can I make sure this question gets deleted?
