In ecocbo: Calculating Optimum Sampling Effort in Community Ecology

PERMANOVA one-way

Description

Calculates observed F and mean squares for the residuals and among sites. This function is a helper for prep_data().

Usage

permanova_oneway(
  x,
  factEnv,
  type = "P",
  method = "bray",
  transformation = "none"
)

Arguments

x	ecological community data.
factEnv	label for the community data.
type	which algorithm to use for the calculation? At the moment, the only option is "P".
method	appropriate distance/dissimilarity metric (e.g. Gower, Bray–Curtis, Jaccard, etc).
transformation	Mathematical function to reduce the weight of very dominant species.

Value

A data frame containing the resulting PERMANOVA table.
