I've tried isnull(), > which is not defined. isnull() is defined in Julia Base. But it's not a vectorized operation: isnull(df[:somevar]) will return false when you seem to be looking for a boolean vector. What you're looking for should work when written as isnull.(df[:somevar]), but currently there's a bug that makes it fail. That's on our TODO list: https://github.com/JuliaStats/NullableArrays.jl/issues/153
