Data manipulation is one of the most common and essential tasks in data analysis. Whether you are working with tabular data, time series, spatial data, or any other kind of data, you need to be able to perform operations such as filtering, grouping, aggregating, joining, reshaping, and more. In the R world, the dplyr package is one of the most popular and powerful tools for data manipulation. It provides a consistent and expressive syntax based on the tidyverse principles, which make it easy to write readable and maintainable code. Many other packages extend its functionality, allowing you to work with large and diverse data sources.
