Previously, under DataArray, I could do df2 = df[!isna(df[:somvar),:] Is there a NullableArray equivalent to isna()? I've tried isnull(), which is not defined. Thanks

Re: [julia-users] Is there a way to use values in a DataFrame directly in computation?

I think the core problem is that the current API + Nullable's is very cumbersome, but the switch to Nullable's will hopefully occur nearly simultaneously with the introduction of new API's that can make Nullable's much easier to deal with. David Gold spent the summer working on one approach tha

There's nothing you can do with comprehensions or generators that you can't do with for loops or functional programming. But there are situations where they are considerably more convenient syntactically. Consider a case where you have several nested for clauses and a filter clause involving all of

This is why, IMHO, Nullables are a mess at the moment. You have to either get(df[1,:A]) or otherwise extract the actual value, since very few things handle Nullables out of the box. On Monday, October 3, 2016 at 8:21:39 AM UTC-7, Min-Woong Sohn wrote: > > I am using DataFrames from master bra
