OVERVIEW

Objective of this assignment is to create a SHINY APPLICATION. I have used data IRIS from R Studio to predict the width of SEPAL and width of PETAL using their respective lengths as predictor. As we change the inut length of Sepal and Petal using input sliders our models predict their widths which is displayed as plots as well as text outputs.

DATA

We are using data Iris from R Studio.

Iris is dataframe having 150 observation and 5 variables.

str(iris)

‘data.frame’: 150 obs. of 5 variables:

$ Sepal.Length: num 5.1 4.9 4.7 4.6 5 5.4 4.6 5 4.4 4.9 …

$ Sepal.Width : num 3.5 3 3.2 3.1 3.6 3.9 3.4 3.4 2.9 3.1 …

$ Petal.Length: num 1.4 1.4 1.3 1.5 1.4 1.7 1.4 1.5 1.4 1.5 …

$ Petal.Width : num 0.2 0.2 0.2 0.2 0.2 0.4 0.3 0.2 0.2 0.1 …

$ Species : Factor w/ 3 levels “setosa”,“versicolor”,..: 1 1 1 1 1 1 1 1 1 1 …

INPUT and OUTPUT

For Input I have used two sliders and two chechbox inputs.

We can slide the inputs sepal length and petal length and also we can chose to show or hide our models 1 & 2 using checkboxes.

For Output we have made plot and text output for each model they use reactive staements to find outputs every time we slide inut . In plots they show respective output inform of point on the line and also this application shows the prediction output for each modelin form of text.
