protective_layers: Create Protective Layers for Design of Experiments (DOEs)

In agricolaeplotr: Visualization of Design of Experiments from the 'agricolae' Package

Create Protective Layers for Design of Experiments (DOEs)

Description

This function generates protective layers around the polygons of an experiment. These layers can be used to plot boundaries, for example, to protect agricultural on-farm experiments from accidental harvesting.

Usage

protective_layers(design, borders = c(0, 3, 5, 10))

Arguments

design	An sf object containing the polygons of the experiment. The coordinate reference system (crs) of the data needs to be in metric distance, not degrees.
borders	A numeric vector specifying the distances (in meters) for which protective layers should be created. The layers will be created with decreasing distances, starting from the largest.

Value

An sf object representing the protective layers around the experiment polygons.

Examples

library(agricolaeplotr)
library(sf)
library(ggplot2)
example("make_polygons")
polygo <- make_polygons(plt, north = 13454206.89, east = 7939183.21)
polygo <- st_transform(polygo, 25832)
pl <- protective_layers(polygo)
# plot experiment shape
ggplot(pl) + geom_sf(fill=c("black","orange","blue","red"))+ theme_minimal()
# write them to kml for Google Maps
# st_write(pl, "boundaries2.kml", append = FALSE)
