Description Usage Arguments Objects from the Class Slots Author(s)

Create a dataset for spatial smoothing splines. Those dataset can be used later by functions s2D for tensor product (natural) cubic splines or p-splines, and scp for estimating spatial smoothing splines models.

Objects can be created by calls of the form `sss(...)`

.

- data
a data-frame containing the variables measured at the locations given by

`coords`

.- coords
a matrix containing the two columns of observed coordinates for the data.

- grid
a grid matrix containing the two columns of coordinates.

- knots
a named list with the design points (knots) in every coordinate. Equivalent to a

`grid.list`

object.- W
a spatial incidence matrix. If

`contract=TRUE`

it is*W_{ij}*, otherwise*W_{ji}*.- contract
logical. The same value as the argument

`contract`

.- regular
logical. If the coordinates are observed at regular points it is

`TRUE`

,`FALSE`

otherwise (missing coordinates in any direction).
