humus: Humus Layer (O-horizon) of the Kola Data

In mvoutlier: Multivariate Outlier Detection Based on Robust Methods

Description

The Kola Data were collected in the Kola Project (1993-1998, Geological Surveys of Finland (GTK) and Norway (NGU) and Central Kola Expedition (CKE), Russia). More than 600 samples in five different layers were analysed, this dataset contains the humus layer.
