In Hy4m/hyplot:

Description

Perform procrutes test quickly and tidy up the data to data frame.

Usage

procrutes_test(
  spec,
  env,
  group = NULL,
  procrutes.fun = "protest",
  spec.select = NULL,
  env.select = NULL,
  use = "everything",
  spec.pre.fun = "identity",
  spec.pre.params = list(),
  env.pre.fun = spec.pre.fun,
  env.pre.params = spec.pre.params,
  seed = 123,
  ...
)

spec, env	data frame object.
group	vector for rows grouping.
procrutes.fun	string, name of procrutes test function. "protest" will use vegan::protest() (default). "procuste.randtest" will use ade4::procuste.randtest(). "procuste.rtest" will use ade4::procuste.rtest().
spec.select, env.select	NULL (default), numeric or character vector index of columns.
use	one of "everything", "complete" or "pairwise".
