## Meuse block

### Description

`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)
```

### 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`
