In r-spatialecology/landscapemetrics: Landscape Metrics for Categorical Map Patterns

Show core area

Description

Show core area

Usage

show_cores(
  landscape,
  directions = 8,
  class = "all",
  labels = FALSE,
  nrow = NULL,
  ncol = NULL,
  consider_boundary = TRUE,
  edge_depth = 1
)

Arguments

landscape	Raster object
directions	The number of directions in which patches should be connected: 4 (rook's case) or 8 (queen's case).
class	How to show the core area: "global" (single map), "all" (every class as facet), or a vector with the specific classes one wants to show (every selected class as facet).
labels	Logical flag indicating whether to print or not to print core labels. boundary should be considered as core
nrow, ncol	Number of rows and columns for the facet.
consider_boundary	Logical if cells that only neighbour the landscape boundary should be considered as core.
edge_depth	Distance (in cells) a cell has the be away from the patch edge to be considered as core cell

Details

The functions plots the core area of patches labeled with the corresponding patch id. The edges are the grey cells surrounding the patches and are always shown.

Value

ggplot

Examples

landscape <- terra::rast(landscapemetrics::landscape)

# show "global" core area
show_cores(landscape, class = "global", labels = FALSE)

# show the core area of every class as facet
show_cores(landscape, class = "all", labels = FALSE)

# show only the core area of class 1 and 3
show_cores(landscape, class = c(1, 3), labels = TRUE)
