makeImputeMethod

(<code>function(data, target, col, ...)</code>)
Function to learn and extract information on column <code>col</code>
out of data frame <code>data</code>. Argument <code>target</code> specifies
the target column of the learning task.
The function has to return a named list of values.

learn

(<code>function(data, target, col, ...)</code>)
Function to impute missing values in <code>col</code> using information
returned by <code>learn</code> on the same column.
All list elements of the return values o <code>learn</code>
are passed to this function into <code>...</code>.

impute

Named list of arguments to pass to <code>learn</code> via <code>...</code>.

args

This is a constructor to create your own imputation methods.

Interface to a large number of classification and
regression techniques, including machine-readable parameter
descriptions. There is also an experimental extension for survival
analysis, clustering and general, example-specific cost-sensitive
learning. Generic resampling, including cross-validation,
bootstrapping and subsampling. Hyperparameter tuning with modern
optimization techniques, for single- and multi-objective problems.
Filter and wrapper methods for feature selection. Extension of basic
learners with additional operations common in machine learning, also
allowing for easy nested resampling. Most operations can be
parallelized.
