In OpenLand: Quantitative Analysis and Visualization of LUCC

Description

A stacked barplot showing net and gross changes of LUC categories during the entire analysed time period.

Usage

netgrossplot(
  dataset,
  legendtable,
  title = NULL,
  xlab = "LUC category",
  ylab = "Area (Km2)",
  legend_title = "Changes",
  changesLabel = c(GC = "Gross change", NG = "Net gain", NL = "Net loss"),
  color = c(GC = "gray70", NG = "#006400", NL = "#EE2C2C"),
  area_km2 = TRUE
)

Arguments

dataset	A table of the multi step transition (lulc_Mulstistep) generated by contingencyTable.
legendtable	A table containing the LUC legend items and their respective color (tb_legend).
title	character. The title of the plot (optional), use NULL for no title.
xlab	character. Label for the x axis.
ylab	character. Label for the y axis.
legend_title	character. The title of the legend.
changesLabel	character. Labels for the three types of changes, defaults are c(GC = "Gross change", NG = "Net gain", NL = "Net loss").
color	character. A vector defining the three bar colors.
area_km2	logical. If TRUE the change is computed in km2, if FALSE in pixel counts.

Value

A bar plot
