Downstream analyses were carried out in R using packages such as vegan, phyloseq and metgenomeSeq, to correlate the composition data with available participant data. Analysis of variance (ANOVA) was performed for baseline values of alpha and beta diversity as dependent variables and treatment group and center as between‐subject factors and the sampling site (buccal/lingual, interproximal, and subgingival. Here are some examples of PCoA on OTU counts using the phyloseq package (based on vegan). Given close linkages between rhizosphere processes and plant nutrition and productivity, understanding how management practices impact this critical zone is of great importance to. otu_table() is a phyloseq function which extract the OTU table from the phyloseq object. These functions include envfit, ordiplot, ordiellipse and ordisurf, and I will explain how to use some of their features here. Normally, one would not compute PCoA on a matrix of Euclidean distances since PCA is a faster method to obtain an ordination of the objects in Y that preserves the Euclidean distance among the objects. DESeq_varstab <-function (phyloseq, design) {# phyloseq = the input phyloseq object that you want to get DESeq transformed counts for # design_variable = the design for the conversion to the DESeq object. It uses the data of the now famous MiSeq SOP by the Mothur authors but analyses the data using DADA2.
