R: Converting Ordered Factors

cut.ordered {cba} | R Documentation

## Converting Ordered Factors

### Description

Reduce the levels of an ordered factor.

### Usage

    ## S3 method for class 'ordered'
    cut(x, breaks, ...)

### Arguments

`x` | an ordered factor.
`breaks` | a logical, character, or index vector of cut points.
`...` | further (unused) arguments.

### Details

If `breaks` is of class `logical` it must have the same length as the number of levels of `x`.

If `breaks` is of class `character` partial matching with the levels of `x` is attempted.

Otherwise `breaks` is assumed to index the levels.

### Value

An ordered factor.
