2 tibble: Modern data frames

Tibbles are a modern reimagining of the trandition data.frame, keeping what time has shown to be effective, and throwing out what is not (stringasFactors = TRUE), with nicer display when obseravtions exceeds 20 rows. The usage of tibble also underlyies one of the principles of the whole tidyverse universe. In most places, I’ll use the term tibble and data frame interchangeably; when I want to draw particular attention to R’s built-in data frame, I’ll call them data.frames.
