list_lsm

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
