You are expecting us to offer advice on the basis of things that we  
cannot see. Show us preferably the output of dput(T) and failing that  
at the very least the output of either dput(T[1, ]) and str(T). It is  
possible that unlist(T[1,1]) or unname(T[1,1]) could be the answer,  
but without better evidence those are wild guesses.
