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.
Examples
landscape <- terra::rast(landscapemetrics::landscape)
# show "global" core area
show_cores(landscape, class = "global", labels = FALSE)
#> $layer_1
#>
# show the core area of every class as facet
show_cores(landscape, class = "all", labels = FALSE)
#> $layer_1
#>
# show only the core area of class 1 and 3
show_cores(landscape, class = c(1, 3), labels = TRUE)
#> $layer_1
