dynRB_Vn: Relative Dynamic Range Box size per dimension and object

Description Usage Arguments Value Note Author(s) References Examples

Description

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

Usage

1
dynRB_Vn(A = A, steps = 201, correlogram = FALSE, row_col = c(2, 2))

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)

Value

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

Note

A tutorial that introduces the functions implemented in the package, explains the outputs, gives examples on how to use the output for follow-up analyses, and finally shows how to visualize the results can be found here: Tutorial dynRB
