sankeyLand: Sankey diagram of LUC transitions (one or multistep)

Description

A sankey showing the one or multi step LUC transitions during the analysed period.

Usage

sankeyLand(dataset, legendtable, iterations = 0)

Value

A sankey diagram

Arguments

dataset

A table of the multi step (lulc_Mulstistep). or one step transitions (lulc_OneStep) generated by contingencyTable.

legendtable

A table containing the LUC legend items and their respective color (tb_legend).

iterations
