Meuse block

Description

meuse.blocks is an object of the class SpatialPolygonsDataFrame that contains the coordinates of 259 artificially defined by putting a grid with 150 m mesh width over the the flood plain area of the river Meuse, near the village Stein. The 259 x 2 data frame contains the covariate dist and the attribute M for each block.

Usage

data(meuse.blocks)

Format

The object contains the following slots:

polygons

an object of the class SpatialPolygons that contains the coordinates of the 259 blocks

data

a 259 x 2 data frame contains:

dist

mean Euclidean distance of the blocks from the river, normalized to the interval [0;1]

M

the (spatial) variance of the mean distance between points, uniformly distributed within the blocks, and the river
