Introduction

I have built a shiny app hosted on shinyapps.io.
This app aims at exploring the well known iris dataset, available with R.

About iris

plot(iris)

plot of chunk unnamed-chunk-1 

names(iris)

[1] "Sepal.Length" "Sepal.Width"  "Petal.Length" "Petal.Width" 
[5] "Species"

Data scientist's components used

  • I used the Shiny dashboard package to make the app good-looking, as I am not HTML / CSS expert: shinydashboard
  • I hosted my code on github

Reactive parts of the app

The main output of the app is a chart which enables the user to visualize iris dataset being clustered (using k-mean algorithm) based on its representation along 2 axes chosen by the user.
The selection of x or y axis, as well as the number of clusters to be created are the 3 responsive elements of this app.
