[R] Extract specific rows from matrix

I have a matrix with 3 years of data (2006, 2009, 2010). I am trying to split this matrix by year so that I have 3 separate matrices. My matrix looks like this:     Q16.1 Year Gender Grade1       3 2006      1     52       2 2006      0     53       3 2006      0     54       3 2006      0     5
