plot_longest_diagonal: Plot the longest diagonal of a field

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

Plot the longest diagonal of a field

Description

This function takes a field and plots the longest diagonal of the field. The field is divided into segments and points are sampled from these segments.

Usage

plot_longest_diagonal(
  field,
  n = 8,
  type = "random",
  n_segments = 2,
  distance_field_boundary = 3,
  width_diagonal_path = 2
)

Arguments

field	An object of class sf representing the field.
n	Integer, the number of sample points along the longest diagonal.
type	Type of sampling. Default is "random".
n_segments	Numeric, the number of segments to divide the longest diagonal (default is 2).
distance_field_boundary	Numeric, the distance to buffer the field for creating the boundary (default is 3.0).
width_diagonal_path	Numeric, the width to buffer the diagonal path (default is 2.0).

Value

• p: A ggplot object showing the field, the buffered field, the buffered line, and the sample points.

• buffered_line: A sf object representing the buffered line.

• my_line: A sf object representing the longest diagonal of the field.

• sample_points: A sf object representing the sampled points.

• length: A numeric value, representing the length of the longest line.

Examples

library(sf)
my_sf <- st_read(system.file("shape/gfn_schlaege.shp", package="agricolaeplotr"))
st_crs(my_sf) <- 25832
field <- my_sf[my_sf$SCHLAG_NR == 170,]
plot_longest_diagonal(field)
