When applying b$omit$empty on a data.frame, the function currently checks if all columns are of character class.

This is not required.

However, we want to drop "", NULL - is there an easy way to check for this?

Turns out checking for NULL is not needed, missing values are not supported in a data.frame (those would be NA).
