Description

About the Workshop Series

In this workshop, we teach different ways to manipulate data in tabular and text forms. We will use both the built-in R functions and the R package ‘dplyr’, which provides powerful high-level operations to summarize and transform data frames. We will also introduce you to “regular expressions”, a powerful notation for expressing text.

You will learn:

  • to create subsets of rows or columns from data frames using dplyr,
  • to select pieces of an object by indexing using element names or position,
  • to change your data frames between wide and narrow formats using the packages reshape2 or tidyr,
  • to work with text data (strings) including pasting strings together, modifying, and manipulating a specific segment in a string of text,
  • to use regular expressions for finding and validating text in R objects and,
  • how substitution patterns can be used for data cleaning.
