as_task: Convert to a Task

In mlr3: Machine Learning in R - Next Generation

Convert to a Task

Description

Convert object to a Task or a list of Task.

The function supports:

• Converting existing Task objects (with optional cloning)

• Converting objects from other packages (e.g., OMLTask from mlr3oml)

• Converting lists of objects to lists of tasks

For constructing tasks from data frames, use the dedicated converters:

• as_task_classif() for classification tasks

• as_task_regr() for regression tasks

• as_task_unsupervised() for unsupervised tasks

Usage

as_task(x, ...)

## S3 method for class 'Task'
as_task(x, clone = FALSE, ...)

as_tasks(x, ...)

## Default S3 method:
as_tasks(x, ...)

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

Arguments

x	(any) Object to convert.
...	(any) Additional arguments.
clone	(logical(1)) If TRUE, ensures that the returned object is not the same as the input x.
