KappaV: Calculates vectorial kappa between two shapes

In vbonhomme/KappaV: Calculates "Vectorial Kappa", an Index of Congruence Between Patchy Mosaics

Description

This function calculates the vectorial Kappa, the associated standard deviation and also returns the confusion matrix calculated between two vectorial landscapes.

Calculates vectorial Kappa, i.e. congruence between two vectorial landscapes.

Usage

KappaV(shp1.path, shp2.path, shp1.fieldID = "ID",
  shp2.fieldID = shp1.fieldID, shp1.fieldOS = "OS",
  shp2.fieldOS = shp1.fieldOS, plot = FALSE, progressBar = TRUE)

Arguments

shp1.path	character. The path to the first shape file.
shp2.path	character. The path to the second shape file.
shp1.fieldID	character. The column name in the .dbf file to indicate the polygons IDs.
shp2.fieldID	character. The column name in the .dbf file to indicate the polygons IDs.
shp1.fieldOS	character. The column name in the .dbf file to indicate the nominal variable of interest.
shp2.fieldOS	character. The column name in the .dbf file to indicate the nominal variable of interest.
plot	logical. Whether to plot the two landscapes.
progressBar	logical. Whether to display a progress bar during calculations.

Details

If not specified the default parameters are shp1.fieldID = "ID", shp2.fieldID = shp1.fieldID, shp1.fieldOS = "OS",shp2.fieldOS = shp1.fieldOS and plot = FALSE

Value

A list with two components: confusion.matrix: the confusion matrix with the corresponding areas. and $kappa.v: a numeric with two values: $Kappa (the value of vectorial Kappa) and $Kappa.sd (the associated standard deviation)
