Raster* Layer, Stack, Brick or a list of rasterLayers.
The number of directions in which patches should be connected: 4 (rook's case) or 8 (queen's case).
tibble
$$CA = sum(AREA[patch_{ij}])$$ where \(AREA[patch_{ij}]\) is the area of each patch in hectares.
TA is an 'Area and edge metric'. The total (class) area sums the area of all patches in the landscape. It is the area of the observation area.
