Source: R/plotting.R
ss_plot.Rd

Creates a visualization of the spatial stratification.

Usage

ss_plot(
  x,
  samples = NULL,
  show_boundaries = TRUE,
  show_centroids = FALSE,
  fill_color = "#80CC80",
  boundary_color = "#CCE5CC",
  sample_color = "black",
  sample_alpha = 0.7,
  sample_size = 2,
  ...
)

Arguments

x

An object of class ss_strata or ss_samples.

samples

Optional ss_samples object to overlay on stratification.

show_boundaries

Logical, whether to show stratum boundaries (default TRUE).

show_centroids

Logical, whether to show stratum centroids (default FALSE).

fill_color

Character, fill color for the study area (default "#80CC80").

boundary_color

Character, color for stratum boundaries (default "#CCE5CC").

sample_color

Character, color for sampling points (default "black").

sample_alpha

Numeric, transparency for sampling points (default 0.7).

sample_size
