But what if I cannot change the positions of each row pairs in A. Sorry I
did not make it very clear.
The two columns in A represent start-and-end or end-

Assuming I understand what you want, which I'm not certain of, here's

I'm not sure how you'd put them in a vector, since there are different
numbers of values for each row of A, so instead I've made a list.

Dear R experts,
I have 2 matix: A& B. I am trying to index B against A - (1) find out B rows
that fall between the col 1 and 2 of A& put them into a new vector SNP.I made
code as below, but I cannot think of a right way to do it. Could anyone help
me with the code? Thanks,Jiang
