%description
Supporting functionality to run 'caret' with spatial or spatial-temporal
data. 'caret' is a frequently used package for model training and
prediction using machine learning. CAST includes functions to improve
spatial or spatial-temporal modelling tasks using 'caret'. It includes the
newly suggested 'Nearest neighbor distance matching' cross-validation to
estimate the performance of spatial prediction models and allows for
spatial variable selection to selects suitable predictor variables in view
to their contribution to the spatial model performance. CAST further
includes functionality to estimate the (spatial) area of applicability of
prediction models. Methods are described in Meyer et al. (2018)
