# new_factor

##### Factor/ordered factor S3 class

A factor is an integer with attribute `levels`

, a character vector. There
should be one level for each integer between 1 and `max(x)`

.
An ordered factor has the same properties as a factor, but possesses
an extra class that marks levels as having a total ordering.

- internal

##### Usage

```
new_factor(x = integer(), levels = character(), ...,
class = character())
```new_ordered(x = integer(), levels = character())

# S3 method for factor
vec_type2(x, y)

# S3 method for ordered
vec_type2(x, y)

# S3 method for factor
vec_cast(x, to)

##### Arguments

- x
Integer values which index in to

`levels`

.- levels
Character vector of labels.

- ..., class
Used to for subclasses.

##### Details

These functions help the base factor and ordered factor classes fit in to
the vctrs type system by providing constructors, coercion functions,
and casting functions. `new_factor()`

and `new_ordered()`

are low-level
constructors - they only check that types, but not values, are valid, so
are for expert use only.
