list_lsm: List landscape metrics

In landscapemetrics: Landscape Metrics for Categorical Map Patterns

List landscape metrics

Description

List landscape metrics

Usage

list_lsm(
  level = NULL,
  metric = NULL,
  name = NULL,
  type = NULL,
  what = NULL,
  simplify = FALSE,
  verbose = TRUE
)

Arguments

level	Level of metrics. Either 'patch', 'class' or 'landscape' (or vector with combination).
metric	Abbreviation of metrics (e.g. 'area').
name	Full name of metrics (e.g. 'core area')
type	Type according to FRAGSTATS grouping (e.g. 'aggregation metrics').
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_c_ca", "lsm_l_ta").
simplify	If true, function names are returned as vector.
verbose	Print warning messages

Details

List all available landscape metrics depending on the provided filter arguments. If an argument is not provided, automatically all possibilities are selected. Therefore, to get all available metrics, use simply list_lsm(). For all arguments with exception of the what argument, it is also possible to use a negative subset, i.e. all metrics but the selected ones. Therefore, simply use e.g. level = "-patch". Furthermore, it is possible to only get a vector with all function names instead of the full tibble.

Value

tibble

Examples

list_lsm(level = c("patch", "landscape"), type = "aggregation metric")
list_lsm(level = "-patch", type = "area and edge metric")
list_lsm(metric = "area", simplify = TRUE)

list_lsm(metric = "area", what = "lsm_p_shape")
list_lsm(metric = "area", what = c("patch", "lsm_l_ta"))
list_lsm(what = c("lsm_c_tca", "lsm_l_ta"))
