Object Not Found Error When Importing a CSV File in R

Introduction

One common error that can stymie even experienced R users is the infamous "object not found" error when importing a CSV file. This error can be frustrating, especially when you're sure the data file is correctly specified. Below, we'll explore some frequent culprits for this issue and provide guidance on how to handle them.

Common Causes

Incorrect File Path
