Show crop distributions maps using a stack for each farming system

Source: R/view_stack.R

To quickly inspect the SPAMc results, view_stack shows crop distribution maps for a selected crop stacking the maps for each farming system. The maps are visualized using leafletjs, which makes it possible to select a number of background tiles (e.g. OpenStreetMap).

view_stack(crp, var, param, viewer = TRUE, polygon = TRUE)

Arguments

crp

Character. Crop for which the maps are shows. crp has to be one of the SPAMc four letter crop codes.

var

Character. The variable to be plotted. var has to be physical area ("pa") or harvested area ("ha").

param

Object of type spam_par that bundles all SPAM parameters, including core model folders, alpha-3 country code, year, spatial resolution, most detailed level at which subnational statistics are available, administrative unit level at which the model is solved and type of model.

viewer

Logical. Should the default web browers be used to show the maps? FALSE will show the maps in the RStudio viewer pane.

polygon

Logical; should the country polygon be overlayed?

Examples

if (FALSE)  view_stack(crop = "maiz", var = "ha", viewer = FALSE,
 polygon = FALSE)
