Description

This data set gives locations and top soil heavy metal concentrations (ppm), along with a number of soil and landscape variables, collected in a flood plain of the river Meuse, near the village Stein. Heavy metal concentrations are bulk sampled from an area of approximately 15 m x 15 m.

Usage

data(meuse.all)

Arguments

Format

This data frame contains the following columns:

sample: sample number
x: a numeric vector; x-coordinate (m) in RDM (Dutch topographical map coordinates)
y: a numeric vector; y-coordinate (m) in RDM (Dutch topographical map coordinates)
cadmium: topsoil cadmium concentration, ppm.; note that zero cadmium values in the original data set have been shifted to 0.2 (half the lowest non-zero value)
copper: topsoil copper concentration, ppm.
lead: topsoil lead concentration, ppm.
zinc: topsoil zinc concentration, ppm.
elev: relative elevation
om: organic matter, as percentage
ffreq: flooding frequency class
soil: soil type
lime: lime class
landuse: landuse class
dist.m: distance to river Meuse (metres), as obtained during the field survey
in.pit: logical; indicates whether this is a sample taken in a pit
in.meuse155: logical; indicates whether the sample is part of the meuse (i.e., filtered) data set; in addition to the samples in a pit, an sample (139) with outlying zinc content was removed
in.BMcD: logical; indicates whether the sample is used as part of the subset of 98 points in the various interpolation examples of Burrough \& McDonnell
