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

In OpenLand: Quantitative Analysis and Visualization of LUCC

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)

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	numeric. Number of iterations in the diagram layout for computation of the depth (y-position) of each node. See sankeyNetwork.

Value

A sankey diagram
