[R] Removing

[bad2101 at columbia.edu]

I think I should be clearer.  Given the matrix of column vectors Age,  
Sex, and Ill

Age=c(11,52,65,59,13,63,70,40,15,33,65,38,62,10,25,32,62,36,11,33,13,7,64,3,65,59,15,62,37,17,35,15,50,40,35,35,36,57,16,68,54,77,72,58,20,17,62,20,52,9,50,8,35,48,25,11,74,12,44,53,37,24,69,7,17,8,11,17,36,21,60,18,14,52,45)
Sex=c("Male","Female","Male","Female","Female","Female","Male","Female","Female","Female","Male","Female","Female","Male","Male","Female","Female","Male","Male","Female","Female","Male","Male","Male","Female","Female","Female","Male","Female","Male","Male","Male","Female","Male","Female","Female","Male","Female","Female","Male","Female","Male","Female","Male","Male","Male","Female","Female","Female","Female","Male","Male","Female","Female","Male","Female","Male","Female","Female","Female","Male","Female","Female","Male","Female","Female","Female","Male","Female","Female","Male","Female","Female","Male","Female")
Ill=c("No","Yes","Yes","Yes","No","Yes","Yes","Yes","Yes","Yes","No","No","No","Yes","No","Yes","Yes","Yes","No","Yes","Yes","Yes","No","Yes","No","Yes","Yes","No","Yes","No","Yes","Yes","Yes","No","No","Yes","No","Yes","Yes","Yes","No","Yes","Yes","Yes","No","No","Yes","Yes","Yes","No","No","Yes","No","Yes","Yes","No","Yes","Yes","Yes","Yes","No","No","No","No","Yes","Yes","No","No","No","Yes","Yes","Yes","No","Yes","Yes")
o=order(Ill)
cbind(Age[o],Sex[o],Ill[o])

I am trying to remove all rows of the matrix in which the element in  
the Ill column vector is "No".  I appreciate any help you have to offer.
