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/package=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.
A data frame with 155 rows and 12 variables.
