%description
Extends the 'mlr3' ecosystem to functional analysis by adding support for
irregular and regular functional data as defined in the 'tf' package.  The
package provides 'PipeOps' for preprocessing functional columns and for
extracting scalar features, thereby allowing standard machine learning
algorithms to be applied afterwards. Available operations include simple
functional features such as the mean or maximum, smoothing, interpolation,
flattening, and functional 'PCA'.
