## Formula Interface for Split

### Description

Implementation of a simple formula interface for the `split` function.

### Usage

    ## S3 method for class 'formula'
     split(x, f, drop = FALSE, data = NULL, ...)

### Arguments

`x` | a formula of the form `y ~ x`.
`f` | a 'factor' in the sense that `as.factor(f)` defines the grouping, or a list of such factors in which case their interaction is used for the grouping.
`drop` | logical indicating if levels that do not occur should be dropped (if `f` is a `factor` or a list). Defaults to FALSE.
`data` | the data frame from which the formula should be evaluated.
`...` | other arguments to be passed to `split`.
