plotsiland.land {siland}

Map of siland result

Description

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

Usage

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

Arguments

x

an object resulting from siland

land

the object of class sf describing the landscape variable, i.e. the land argument in the call to the siland function that computed x

data

the dataframe describing response variable and the local variables, i.e. the data argument in the call to the siland 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
