# predictors

##### List predictors used in the model

This class uses a model fit to determine which predictors were used in the final model.

- Keywords
- models

##### Usage

`predictors(x, ...)`## S3 method for class 'default':
predictors(x, ...)

## S3 method for class 'formula':
predictors(x, ...)

## S3 method for class 'list':
predictors(x, ...)

## S3 method for class 'rfe':
predictors(x, ...)

## S3 method for class 'sbf':
predictors(x, ...)

## S3 method for class 'terms':
predictors(x, ...)

## S3 method for class 'train':
predictors(x, ...)

##### Arguments

- x
- a model object, list or terms
- ...
- not currently used

##### Details

For `randomForest`

, `cforest`

, `ctree`

, `rpart`

, `ipredbagg`

, `bagging`

, `earth`

, `fda`

, `pamr.train`

, `superpc.train`

, `bagEarth`

and `bagFDA`

, an attempt was made to report the predictors that were actually used in the final model.

The `predictors`

function can be called on the model object (as opposed to the `train`

) object) and the package will try to find the appropriate coed (if it exists).

In cases where the predictors cannot be determined, `NA`

is returned. For example, `nnet`

may return missing values from `predictors`

.

##### Value

- a character string of predictors or
`NA`

.
