Working with data is at the centre of programming in R. In addition to core functionality of base R, many new packages, such as tidyverse collection provide advanced data manipulation facilities and enhanced experience of working with tabular data. In this week we will focus on data frame and its tidyverse cousin tibble. We will also discuss formats of data storage and functions for data I/O and descriptive analysis.
