Compute Gower dissimilarity between two site vectors

Source: R/helper_indices.R
orderwise_diss_gower.Rd

Calculates the Gower dissimilarity (a bounded 0–1 measure) between two numeric vectors (e.g., species abundances) using the cluster::daisy() function. When the second vector is NULL (order 1), returns NA_real_ since a pairwise comparison is not meaningful.

Usage

orderwise_diss_gower(vec_from, vec_to = NULL)

Arguments

vec_from

Numeric vector representing the first site's attributes (e.g., species counts or trait values).

vec_to

Optional numeric vector for the second site; if NULL, the function returns NA_real_.

Value

A single numeric dissimilarity value between 0 and 1, or NA_real_ if vec_to is NULL.
