R programming for beginners - Manipulate data using the tidyverse. Select, filter and mutate.

This video tutorial introduces R programming, focusing on accessing and using datasets, particularly the Star Wars dataset. It covers data manipulation using the Tidyverse package, including selecting variables, filtering data, and calculating the Body Mass Index (BMI). The tutorial demonstrates how to analyze gender differences in BMI using R's pipe operators and functions like mutate and summarize.
