R help - Dec 2010 - 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     55       3 2006      1    
56       2 2006      0     57       3 2006      0     58       3 2006      1    
59       3 2006      0     510      3 2006      0     511      3 2006      0    
512      2 2006      0     5
Thanks
