library(nycflights13)# A package that seamlessly integrates code, data analysis, and text to create dynamic and reproducible reports and documents.library(knitr)# A package that simplifies data manipulation with intuitive functions, making it indispensable for data wrangling tasks.library(dplyr)print(flights)
Lines 1–7: We load three packages.
Line 9: We print the data frame.
