landscapemetrics (version 1.2)

scale_window: scale_window

Description

Metrics on changing sample scale

Usage

scale_window(landscape, percentages_col, percentages_row, what, stat,
  verbose, progress, ...)
# S3 method for RasterLayer
scale_window(landscape, percentages_col = c(2, 4,
  8, 16, 32, 64, 100), percentages_row = NULL, what, stat,
  verbose = TRUE, progress = FALSE, ...)
# S3 method for RasterStack
scale_window(landscape, percentages_col = c(2, 4,
  8, 16, 32, 64, 100), percentages_row = NULL, what, stat,
  verbose = TRUE, progress = FALSE, ...)
# S3 method for RasterBrick
scale_window(landscape, percentages_col = NULL,
  percentages_row = NULL, what, stat, verbose = TRUE,
  progress = FALSE, ...)
# S3 method for stars
scale_window(landscape, percentages_col = NULL,
  percentages_row = NULL, what, stat, verbose = TRUE,
  progress = FALSE, ...)
# S3 method for list
scale_window(landscape, percentages_col = NULL,
  percentages_row = NULL, what, stat, verbose = TRUE,
  progress = FALSE, ...)

Arguments

landscape

Raster* Layer, Stack, Brick 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().

Value

tibble

Details

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

Please be aware that the output is sligthly different to all other lsm-function of landscapemetrics.

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.
