Data Manipulation

We will go through the main activities one have to face in order to overcome most common data cleaning/wrangling problems.

R has an ecosystem of packages, the tidyverse, each specialized in a single task:

• readr for importing data from various sources;
• tidyr and dplyr for data wrangling;
• ggplot2 for plotting;
• and others.

In Python, it is possible to accomplish almost every data manipulation task with the Pandas package.
