Hi Jason, I’m surprised that df[: 2] works: that seems almost like a bug.
To get column B, either of the following should work on a new copy of DataFrames: df[2] df[:B] If you have a slightly older copy of DataFrames (like you’d get for Julia 0.2), this works df[2] df[“B”] Hope that helps. — John On Feb 28, 2014, at 6:36 PM, Jason Solack <jaysol...@gmail.com> wrote: > Hello all, I'm trying to select a column from a DataFrame using a variable... > something like this > > df = DataFrame(A=[1:10], B=[11:20]) > > when i do this: > > df [ : 2] > > i select column B > > if i do this: > > t = 2 > df [ : t] > > i get an error > > Error Key not found :t > > what am i missing?? > > Thank you in advance, > > Jason
