DataFrames dropped DataArrays for NullableArrays #44

Open phaverty opened 8 years ago

phaverty commented 8 years ago

DataFrames has switched from DataArrays and PooledDataArrays to NullableArrays and CategoricalArrays. rjulia should switch too. I think it would be very similar code.

armgong commented 7 years ago

yes, but the we need carefully read the dataframe docs ,and then change rjulia

phaverty commented 7 years ago

It looks like DataFrames will make the move in a few weeks. https://discourse.julialang.org/t/announcement-dataframes-0-9-0-planned-for-february/266

I have new idea about rjulia , thinking using RCall.jl to write rjulia2, so we don't need so much c code to do conversion.

already write a prototype https://github.com/armgong/rjulia2

I will try it during "Chinese new year" vacation , I will start this job from 2017-1-22 ,hope finish it in the vacation.

Excellent, I think using RCall.jl as much as possible is the way to go. The best thing about julia is not writing C anymore, I believe. I'm looking forward to experimenting with rjulia2.
