Fortify Rényi accumulation curves

Prepares a fortified version of results from vegan::renyiaccum() objects.

# S3 method for class 'renyiaccum'
fortify(model, data, ...)

Arguments

model

an object of class vegan::renyiaccum().

data

original data set. Currently ignored.

...

additional arguments passed to other methods. Ignored in this method.

Value

A data frame (tibble) is returned. What is returned depends on how vegan::renyiaccum() was called. If raw = FALSE, then a data frame with columns site, scale, mean, std_dev, min, max, q2.5, and q97.5, containing the accumulated sites, the Rényi scale, and summary statistics of the Rényi accumulation curves. An additional column collector will be present if collector = TRUE was used in the vegan::renyiaccum() call. If raw = TRUE, then a data frame with columns site, permutation, scale, and diversity, containing the site and permutation identifiers, Rényi scale, and the Rényi diversity, respectively.
