CV_iterative_clustering
                        Cross validation of the iterative Hartigan-Wong
                        k-means clustering.
CV_results              Compute the error or plot the stability values
                        after 'CV_iterative_clustering()'.
clr                     Detected ASV from multiple individuals at four
                        different sampling times.
iterative_clustering    Iterative Hartigan-Wong k-means clustering.
metadata_groups         Easily extract groups of individuals from
                        metadata variables.
paired_times            Generate a subset matrix with paired times.
pre_radarPC             Compute the PCA to the 'paired_times()' output
                        previously to visualize radar charts of
                        principal components.
radarPC                 Plot a radar chart of paired samples from one
                        individual or from different groups.
st_evolution            Generate boxplots of the stability evolution
                        throughout sampling times by groups
st_heatmap              Plot a heatmap of the stability results
st_previz               Process the 'stabilitas()' output to a new
                        format ready for the visualization functions.
st_scatter              Plot a scatter and side boxplot of the
                        stability results
stabilitas              Extract the stability results of individuals
                        from the output of 'iterative_clustering()'.
