meuse.blocks is an object of the class
“SpatialPolygonsDataFrame” that contains the coordinates
of 259 artificially defined (mostly square) blocks obtained by intersecting
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 (spatial variance of
sqrt(dist)) for each block.
Usage
data(meuse.blocks)
Arguments
Format
The object contains the following slots:
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 sqrt(dist)
within the blocks, see Hofer & Papritz (2011).
polygons
an object of the class SpatialPolygons that
contains the coordinates of the 259 blocks, see
SpatialPolygons.
