The str_sub() function | Text Manipulation with the stringr package in R

This video tutorial focuses on manipulating text in R, specifically using the STR_sub function to extract parts of strings. The instructor demonstrates this with the mtcars dataset, showing how to create a new variable for car models and extract the first three letters of each model name. The video also covers loading the tidyverse and GT extras packages to create and format tables, providing a practical example of data manipulation and presentation in R.
