Is this a bug?
If not, I am curious to know why '[<-.data.frame' was designed to yield
a.frame$y != a.frame$z rather than refusing to carry out the operation at
all.
> a.frame <- data.frame( x=letters[1:5] )
> a.frame[ 2:5, "y" ] <- letters[2:5]
> a.frame[[ "z" ]][ 2:5 ] <- letters[2:5]
> a.frame
x y z
1 a b <NA>
2 b c b
3 c d c
4 d e d
5 e <NA> e
