Creating/running your own complex functions based on any formula, & Data Visualization in R [3 of 4]

Objectives

Why do you need to create your own functions and why data visualization & analysis in R?

1. Creating functions.

2. Adding extra complexity to functions using loops and apply functions.

3. Create a complex function to compute descriptive summaries of all variables of data with appropriate graphs.

4. Perform correlation analysis based on all the numerical variables with informative correlation matrix plots.

5. Data visualization.
