# cut.integer: Convert integer vector to Factor In rccmisc: Miscellaneous R Functions for Swedish Regional Cancer Centers

## Description

S3-method for cut applied to integer vectors where all outcome factors are integer intervals.

## Usage

 ```1 2``` ```## S3 method for class 'integer' cut(x, ...) ```

## Arguments

 `x` integer vector `...` further arguments passed to or from other methods

## Value

If `cut.default(x, ...)` returns only intger intervals, these are formated in a more natural way and returned as an ordered factor. If non integer interval limits occur, the output of `cut.default(x, ...)` is retured as is.

## Examples

 ```1 2 3``` ```cut.default(1:100, seq(0, 100, 20)) # Gives a quite unnatural output cut(1:100, seq(0, 100, 20)) # Gives nicer and ordered output cut(1:10, 3) # no integer intervals and therefor same as cut.default ```

### Example output
