Since more packages want to extend `DataFrame` type what is needed is: * define a minimal API that `AbstractDataFrame` needst to support; * review all code base in DataFrames.jl to...
For interoperability with `DTable` we have discussed with @krynju that it would be nice to add `Reduce` wrapper to the mini-language. The working idea is that `src => Reduce(f) =>...
`DataFrames` is great as an exploration tool, but then when we found something that works I just want to make sure that things are well structured and reproducible. Then is...
I have a function `myfun` that operates on one or more rows from my dataframe, and returns a Tables compliant output. The columns will not always be the same for...
Currently `describe(df, :mean)` is allowed but not `describe(df, mean)`, which would allow users to provide their own describing functions.
Currently we precompile only for `UInt32`.
