[Solved] Meaning of these R codes? Are they correlated?

Question

The first line does the cluster analysis, and stores the cluster labels in a component called cluster_iris$cluster which is just a vector of numbers.

The second line puts that cluster number as a categorical label onto the rows of the original data set. So now your iris data has all the petal and sepal stuff and a cluster index in a column called "ClusterM".
