a 2-dimensional matrix or data frame

clusters

numeric vector of length equal to the number of rows of the data, which is the result of a clustering method

centroids_medoids

a matrix of centroids or medoids. The rows of the centroids_medoids should be equal to the length of the unique values of the clusters and the columns should be equal to the columns of the data.

Examples

# data(dietary_survey_IBS)

# dat = dietary_survey_IBS[, -ncol(dietary_survey_IBS)]

# dat = center_scale(dat)

# pca_dat = stats::princomp(dat)$scores[, 1:2]

# km = KMeans_rcpp(pca_dat, clusters = 2, num_init = 5, max_iters = 100)

# plot_2d(pca_dat, km$clusters, km$centroids)
