dynRB_Vn: Relative Dynamic Range Box size per dimension and object

Description

Function returns Dynamic Range Box size of each dimension \(n\). Number of dynamic range boxes (steps) can be adjusted. Default: steps = 201

Usage

dynRB_Vn(A = A, steps = 201, correlogram = FALSE, row_col = c(2, 2))

Value

Data frame containing the summarized niche length for each object and dimension.

Arguments

A

Data frame, where the first column is a character vector and the other columns are numeric vectors.

steps

Number of range boxes. Default: steps = 201

correlogram

If TRUE, the correlogram for each species is shown. If FALSE, no correlogram is shown. Default: correlogram = FALSE

row_col

Number of rows and columns of the figures (correlogram for each species). Default: row_col = c(2, 2)
