plotFsiland.land

Map of Fsiland result

Description

Function creating a map of Fsiland result, i.e. estimatied spatial influence of each landscape variable or for the cumulative effect of all variables.

Usage

plotFsiland.land(x, land, data, var = 0, lw = 100, xlim=NULL, ylim=NULL,plot=T)

Arguments

`x`	an object resulting from `Fsiland`
`land`	the object of class sf describing the landscape variable, i.e. the `land` argument in the call to the `Fsiland` function that computed `x`
`data`	the dataframe describing response variable and the local variables, i.e. the `data` argument in the call to the Fsiland function that computed `x`.
`var`	a vector containing the numbers (numeric) of the mapped landscape variables. If `var=0` (by default), the cumulative effect of all landscape variables is represented.
`lw`	the number of pixels on x-axis and y-axis for the graphical representation. A too high value can lead to memory allocation problems. By default lw=100.
`xlim`	a length-2 numeric vector, lower and upper limits of x-axis.
`ylim`	a length-2 numeric vector, lower and upper limits of y-axis.
`plot`	a logical (TRUE by default). If TRUE, the result is a graphic. If FALSE, the result is a dataframe of the cumulative spatial influence of the landscape variable(s) var.

Value

an object of class ggplot

Examples

data(dataSiland)
data(landSiland)
resF=Fsiland(obs~x1+L1+L2,land=landSiland,data=dataSiland,sif="exponential")
plotFsiland.land(x=resF,land=landSiland,data=dataSiland)
plotFsiland.land(x=resF,land=landSiland,data=dataSiland,var=1,lw=20)
plotFsiland.land(x=resF,land=landSiland,data=dataSiland,var=2,lw=20)
