Deprecated methods for transformation, fit, and prediction. These are mirrors of the corresponding ml-transform-methods.

sdf_predict(x, model, ...)
sdf_transform(x, transformer, ...)
sdf_fit(x, estimator, ...)
sdf_fit_and_transform(x, estimator, ...)

## Arguments

x |
A `tbl_spark` . |

model |
A `ml_transformer` or a `ml_model` object. |

... |
Optional arguments passed to the corresponding `ml_` methods. |

transformer |
A `ml_transformer` object. |

estimator |
A `ml_estimator` object. |

## Value

`sdf_predict()`

, `sdf_transform()`

, and `sdf_fit_and_transform()`

return a transformed dataframe whereas `sdf_fit()`

returns a `ml_transformer`

.
