Data mining is the extraction of different data of intriguing as such (constructive, relevant, constructive, previously unexplored and considerably valuable) patterns or information from very large stack of data or different dataset. In other words, it is the experimental exploration of associations, links, and mainly the overall patterns that prevails in large datasets but is hidden or unknown. So, to explore the performance analysis using different clustering techniques we used R Language. This R language is a tool, which allows the user to analyse the data from various and different perspective and angles, in order to get a proper experimental results and in order to derive a meaningful relationships. In this paper, we are studying, analysing and comparing various algorithms and their techniques used for cluster analysis using R language. Our aim in this paper, is to present the comparison of 5 different clustering algorithms and validating those algorithms in terms of internal and external validation such as Silhouette plot, dunn index, Connectivity and much more. Finally as per the basics of the results that obtained we analyzed and compared, validated the efficiency of many different algorithms with respect to one another.
