MeuseData: Meuse river data set
Description
This data set gives locations, top soil heavy metal concentrations (ppm) and other variables, collected in a flood plain of the river Meuse.
For details on this dataset, see meuse.all in https://cran.r-project.org/web/packages/gstat/gstat.pdf. This version of the dataset
includes 155 observations. Moreover, a definition of the domain's boundary is provided through the file {MeuseBorder},
as it is used in many examples to illustrate fdaPDE features.
- sample: original sample number. In this version of the dataset some observations has been left out because not indicative, or outliers.
- x: numeric vector indicating the x-coordinate (m) in RDM (Dutch topographical map coordinates).
- y: numeric vector indicating the y-coordinate (m) in RDM (Dutch topographical map coordinates).
- cadmium: topsoil cadmium concentration (ppm).
- copper: topsoil copper concentration (ppm).
- lead: topsoil lead concentration (ppm).
- zinc: topsoil zinc concentration (ppm).
- elev: relative elevation.
- dist.log(m): logarithm of the distance to river Meuse (metres), as obtained during the field survey.
- om: organic matter, as percentage.
- ffreq: flooding frequency class.
- soil: soil type.
