WebbAnalysis of Similarities Description. Analysis of similarities (ANOSIM) provides a way to test statistically whether there is a significant difference between two or more groups of sampling units. Usage anosim(x, grouping, permutations = 999, distance = "bray", strata = NULL, parallel = getOption("mc.cores")) Arguments Webb5 mars 2024 · The NMDS result (Fig. 5a) together with the cluster analysis with SIMPROF (Fig. 5b) show a clear distinction in two clusters, a small one for the few samples from the photic zone and a more widely scattered one for all aphotic stations (stress = 0.11). In the SIMPROF analysis (Fig. 5b), the two respective main branches diverge at height 3.48.
