Tidy and glance methods for ordinations — tidy.td

tidy() returns one set of ordination scores as a tibble, and glance() a one-row summary of the ordination.

Usage

# S3 method for class 'td_ordination'
tidy(
  x,
  display = c("sites", "species", "vectors", "centroids", "axes", "envfit"),
  ...
)

# S3 method for class 'td_ordination'
glance(x, ...)

Arguments

x: A td_ordination from ord_fit().
display: Scores to return: "sites", "species", "vectors" (environmental arrows), "centroids" (factor levels), "axes" (eigenvalues and variation explained) or "envfit" (fit of passive variables).
...: Not used.

Value

A tibble.
