R Programming for Statistics and Data Science - Introduction - Data Frames

This video tutorial covers essential data manipulation techniques in R, focusing on data frames. It begins with importing data frames, followed by methods to understand their structure using functions like str and summary. The tutorial then explains how to access and extend data frames by adding new observations or variables. It addresses handling missing data, a common real-world issue, and concludes with exporting data frames for sharing.
