lsm_l_condent

Conditional entropy (landscape level)

Description

Conditional entropy \[H(y|x)\]

Usage

lsm_l_condent(landscape, neighbourhood = 4, ordered = TRUE, base = "log2")

Arguments

landscape

Raster* Layer, Stack, Brick, SpatRaster (terra), stars, or a list of rasterLayers.
neighbourhood

The number of directions in which cell adjacencies are considered as neighbours: 4 (rook's case) or 8 (queen's case). The default is 4.
ordered

The type of pairs considered. Either ordered (TRUE) or unordered (FALSE). The default is TRUE.
base

The unit in which entropy is measured. The default is "log2", which compute entropy in "bits". "log" and "log10" can be also used.

Details

Complexity of a landscape pattern configuration. It measures a only a geometric intricacy (configurational complexity) of a landscape pattern.

Value

tibble
