ranked.ix['Target', 0:3] gives KeyError: 'Target'

[posttenebre]

I ran into an issue when running

# nf = eleven.calculate_nf(censored, ranked.ix['Target', 0:3], 'Control'
>> KeyError: 'Target'

I found that using ranked.loc[ranked.index[[0, 1, 2]], 'Target'] instead of ranked.ix['Target', 0:3] solved the problem.

I am simply adding this to the issues in case anyone else has the same problem.
