I can't get either subset syntax working for some reason. I tried to
Pkg.installed("DataFrames")
v"0.5.7"
df = DataFrame(A = 1:4, B = ["M", "F", "F", "M"])
sub(df,:(A .== "M"))
`getindex` has no method matching getindex(::SimpleIndex, ::Expr)
while loading In[72], in expression starting on line 13
in sub at
/Users/arshakn/.julia/v0.3/DataFrames/src/subdataframe/subdataframe.jl:97
df[:(A % 2 .== 0),:]
`getindex` has no method matching getindex(::DataFrame, ::Expr,
::UnitRange{Int64})
