## Define a model for the spatial behaviour of the GEV parameters

### Description

This function defines the model for the spatial behaviour of the GEV parameter.

### Usage

    modeldef(data, formula)

### Arguments

`data` | A matrix representing the data. Each column corresponds to one location.
`formula` | A R formula. See details for further details.

### Value

need to be documented

### Examples

    ## 1- A design matrix from a classical linear model
    n.site <- 5
    coord <- matrix(rnorm(2*n.site, sd = sqrt(.2)), ncol = 2)
    colnames(coord) <- c("lon", "lat")
    loc.form <- loc ~ lat + I(lon^2)
    modeldef(coord, loc.form)

    ## 2- A design and penalization matrix from a penalized smoothin spline
    x <- sort(runif(10, -2, 10))
    n.knots <- 3
    knots <- quantile(x, prob = 1:n.knots / (n.knots + 2))
    modeldef(x, y ~ rb(x, knots = knots, degree = 3, penalty = 1))
