## Common operations on DataFrame objects

### Description

Common operations on DataFrame objects.

### Splitting

In the following code snippets, `x` is a `DataFrame`.

  `split(x, f, drop = FALSE)`: Splits `x` into a `CompressedSplitDataFrameList`, according to `f`, dropping elements corresponding to unrepresented levels if `drop` is `TRUE`.

  `mstack(..., .index.var = "name")`: Stacks the data frames passed as through ..., using `.index.var` as the index column name. See `stack`.
