Metrics on changing sample scale

Usage

scale_window(

  percentages_row = NULL,
  what,
  stat,
  verbose = TRUE,
  progress = FALSE,
  ...
)

Arguments

landscape	Raster* Layer, Stack, Brick, SpatRaster (terra), stars, or a list of rasterLayers.
percentages_col	2-column matrix with coordinates or SpatialPoints.
percentages_row	String specifying plot shape. Either "circle" or "square"
what	Selected level of metrics: either "patch", "class" or "landscape". It is also possible to specify functions as a vector of strings, e.g. what = c("lsm_l_mutinf", "lsm_l_ta").
stat	The function to be applied. See Details
verbose	If TRUE, warnings are printed.
progress	Print progress report.
...	Arguments passed on to calculate_lsm().

Details

This function calculates the selected metrics in moving windows over the provided landscape.

The metrics can be specified by the arguments what, level, metric, name and/or type (combinations of different arguments are possible (e.g. ⁠level = "class", type = "aggregation metric"⁠). If an argument is not provided, automatically all possibilities are selected. Only metrics on landscape level are supported for this function.
