Distance-Based Redundancy Analysis

Distance-based Redundancy Analysis (db-RDA) is a constrained multivariate ordination that is related to RDA but allows the use of alternative distance matrices.

Description

Distance-based Redundancy Analysis (db-RDA) is a constrained multivariate ordination that is related to RDA but differs in that it operates on dissimilarity matrices derived from the response variables, making it suitable for datasets where Euclidean distances may not adequately represent ecological dissimilarities.

Example

wetlands <- readRDS("wetlands.rds")

library(vegan)

dbrda_ord <- dbrda(wetlands$cross ~ groundwater + tmean + tseason + prsum +
    prseason,
        data = wetlands$env, dist = "bray")

plot(dbrda_ord)
