K-Means Clustering Algorithm From Scratch using R Programming Language

K-Means Clustering code from scratch using R programming language.

Required Packages

ggplot2 for plotting the clustering result in each iteration

Dataset

There are 2 sample dataset in this project, they are dataset 1 and dataset 2.
Each dataset consist of N rows data and 2 columns represent the x-axis and and y-axis.

Running the code

The code is designed to cluster dataset 2 into 3 clusters. If you want to change either dataset or the final number of clusters on another dataset samples, change the following parameters:

Dataset:

Change the following code in line 5 into desired dataset filename.

test1_data <- read.table("D:/test2_data.txt", quote="\"", comment.char="")

Number of Clusters:

Change the following code in line 10-12 into desired number of clusters.
