Splits numeric features into quantile bins.

`R6Class`

object inheriting from `PipeOpTaskPreprocSimple`

/`PipeOpTaskPreproc`

/`PipeOp`

.

PipeOpQuantileBin$new(id = "quantilebin", param_vals = list())

`id`

::`character(1)`

Identifier of resulting object, default`"quantilebin"`

.`param_vals`

:: named`list`

List of hyperparameter settings, overwriting the hyperparameter settings that would otherwise be set during construction. Default`list()`

.

Input and output channels are inherited from `PipeOpTaskPreproc`

.

The output is the input `Task`

with all affected numeric features replaced by their binned versions.

The `$state`

is a named `list`

with the `$state`

elements inherited from `PipeOpTaskPreproc`

, as well as:

`bins`

::`list`

List of intervals representing the bins for each numeric feature.

The parameters are the parameters inherited from `PipeOpTaskPreproc`

, as well as:

`numsplits`

::`numeric(1)`

Number of bins to create. Default is`2`

.

Uses the `stats::quantile`

function.
