K Means Clustering is an unsupervised learning algorithm that tries to cluster data based on their similarity. Unsupervised learning means that there is no outcome to be predicted, and the algorithm just tries to find patterns in the data. In k means clustering, we have the specify the number of clusters we want the data to be grouped into.

Required R packages and functions. The standard R function for k-means clustering is kmeans () [ stats package], which simplified format is as follow: kmeans (x, centers, iter.max = 10, nstart = 1) x: numeric matrix, numeric data frame or a numeric vector.

In R, we typically use the hclust() function to perform hierarchical cluster analysis. hclust() will calculate a cluster analysis from either a similarity or dissimilarity matrix, but plots better when working from a dissimilarity matrix. We can use any dissimilarity object from dist(), vegdist(), or dsvdis().

In clustering or cluster analysis in R, we attempt to group objects with similar traits and features together, such that a larger set of objects is divided into smaller sets of objects. The objects in a subset are more similar to other objects in that set than to objects in other sets.
