I have a project in R about High value customers identification for an E-Commerce company.Everything is in the attachment.

 write a small reflective essay (one to two paragraphs in a Microsoft Word document) in which you will discuss the problem-solving approaches and relevance of the programming concepts used in the script. Collectively, all four small scripts and reflective essays will demonstrate your ability to engage in the fundamental scripting and problem-solving approaches that are represented by the course outcomes:  IT-140-01: Apply appropriate data structures to store and manipulate data for solving computational problems   IT-140-02: Utilize branches and loops to insert decision points for managing the execution of code   IT-140-03: Utilize functions for producing organized, reusable code   IT-140-04: Write accurate regular expressions that search for specific patterns in text material   IT-140-05: Explain problem solving approaches required for implementing and troubleshooting scripting tasks
