 This flexibility allows us to accept arbitrarily complex objects as columns, which is often the case in Bioconductor objects. Also check out Bioconductor's [**S4Vectors**](https://bioconductor.org/packages/S4Vectors) package, which implements the `DFrame` class on which `BiocFrame` was based.

 To retrieve a subset of the data in the `BiocFrame`, we use the subset (`[]`) operator.

 Warnings are raised when properties are directly mutated. These assignments are the same as calling the corresponding `set_*()` methods with `in_place = True`.
 It is best to do this only if the `BiocFrame` object is not being used anywhere else;
 otherwise, it is safer to just create a (shallow) copy via the default `in_place = False`.

 Similarly, we could set or replace columns directly:
