My ShinyApp for Iris dataset

The application for Iris dataset was built as course project of Developing Data Products.

The App is avalaible at: https://grissellbaron.shinyapps.io/Assignment4/.

Source code for ui.R and server.R are avalaible on the GitHub repo: https://github.com/LaylaGrisell/CourseraDevelopingDataProducts/.

This famous (Fisher's or Anderson's) iris data set gives the measurements in centimeters of the variables sepal length and width and petal length and width, respectively, for 50 flowers from each of 3 species of iris. The species are Iris setosa, versicolor, and virginica.

This application helps us to visualize the histogram for 4 variables: Sepal.Length, Sepal.Width, Petal.Length and Petal Width.

The user selects the variable that he wants to graph.

In addition, the user can also select the number bins of histogram and if wants the histogram to be grouped by Species with the options “Yes” and “No” in the section “Grouping by Species”.
