volTriPoints: Solute plume concentration data set.

In deldir: Delaunay Triangulation and Dirichlet (Voronoi) Tessellation

Solute plume concentration data set.

Description

Example solute plume concentration data set associated with the GWSDAT (“GroundWater Spatiotemporal Data Analysis Tool”) project https://protect-au.mimecast.com/s/demRC91WzLH6qo3TorzN7?domain=gwsdat.net. The deldir package is used in this project as part of a numerical routine to estimate plume quantities (mass, average concentration and centre of mass).

Usage

volTriPoints

Format

A data frame with 232 observations on the following 3 variables.

x

The x-coordinates of the centres of mass of the plumes.

y

The y-coordinates of the centres of mass of the plumes.

z

The plume concentrations.

Details

This data set played a critical role in revealing a bug in the Fortran code underlying the deldir() function.

Source

These data were kindly provided by Wayne W. Jones of the GWSDAT project. The data set was originally named Vol.Tri.Points; the name was changed so as to be more consistent with my usual naming conventions.
