installing FastGroupBy

[jangorecki]

installation of FastGroupBy package.
I tried two ways mentioned in readme and got following errors

julia> Pkg.add("FastGroupBy")

is that install procedure up to date? how should I install it?
I am on Ubuntu 16.04

[xiaodaigh]

This hasn't been updated for Julia v1.0.

[xiaodaigh]

@jangorecki If you trying to build some benchmarks, can I suggest that you use the DataFrames.jl and JuliaDB.jl's native group-by? Because eventually these functions will be contributed back to those packages.

[xiaodaigh]

See #9

[xiaodaigh]

@jangorecki This package is now Julia v1 ready. Please note that this package should signficantly improve upon the performance of group-by integer IDs but should be slower than DataFrames.jl for grouping by Strings.

[jangorecki]

AFAIU it is going to be used in DataFames sooner or later?

[xiaodaigh]

It might be a while, because I am unfamiliar with the DataFrame architecture, so I won't be able to contribute to DataFrames any time soon. But people in the DataFrames.jl circle are aware of my approach.

I think this should be tested in the group-by benchmarks too repo as well.

Also adding categorical factors would be nice.
