A 2x19 matrix of vertices for the boundary of a region representing a lake almost divided in half by a causeway. This was used in a simulation in the paper of Barry and McIntyre (2011).
The first item, polygon2, is 35x2 matrix describing the boundary of a region. The second, grid2, is a set of 59 locations for simulated values of a response variable. The third item, Z, is a vector of responses. This dataset was created to test and illustrate the non-parametric lattice based regression estimator. See the example for function createNparReg.
Three 2-column matrices. The first is a set of vertices of a boundary polygon encompassing a region. The other two, hole1 and hole2, are holes in the region. This example dataset is used to illustrate the situation where there are holes in the region where a density or nonparametric regression is to be applied. It is used in the example of the function areaRegion.
