WebPrincipal component analysis (PCA) and redundancy analysis (RDA) were used to evaluate the effects of the phenolic acid content on soil environmental factors. The stats, ggplot2 and vegan packages in R software, version 4.1.1 were used to draw the graphs (R Core Team, 2024). One-way ANOVA was used for analysis after a normal distribution test. WebApr 10, 2024 · Distance based RDA (db-RDA) This is RDA applied to the matrix of sample scores calculated by principal coordinate analysis (PCoA). The raw species data are first converted into a dissimilarity matrix using a selected dissimilarity metric, and this matrix is submitted to PCoA.

WebJun 12, 2024 · Redundancy analysis (RDA) is an analytic method to deal with this type of directionality. Unfortunately, current implementations of RDA cannot deal optimally with the high dimensionality of omics data (⁠ p ≫ n ⁠).
