In this article, we include some of the common problems encountered while executing clustering in R. Cluster Analysis. Finding similarities between data on the 

Cluster Analysis in R Clustering is one of the most popular and commonly used classification techniques used in machine learning. 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.

1. Agglomerative Hierarchical Clustering; 2. Relational clustering/ Condorcet method; 3. k-means clustering  The R-Squared value shows proportion of variance in the cluster assignment that is explained by the each of the clustering variables.

Cluster Analysis in R: Practical Guide. Cluster analysis is one of the important data mining methods for discovering knowledge in multidimensional data. The goal of clustering is to identify pattern or groups of similar objects within a data set of interest.

For computing hierarchical clustering in R, the commonly used functions are as follows: hclust  ClustR: A Space-Time Cluster Analysis R Package for Individual-level Data. Epidemiology.

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.

Cluster Analysis R has an amazing variety of functions for cluster analysis. In this section, I will describe three of the many approaches: hierarchical agglomerative, partitioning, and model based. While there are no best solutions for the problem of determining the number of clusters to extract, several approaches are given below.
