In this post in the R:case4base series we will look at string manipulation with base R, and provide an overview of a wide range of functions for our string working needs. We will use simple examples to learn to perform basic string operations, concatenate strings, work with substrings, switch cases, quote, find and replace within strings and more. Some interesting bonuses will also be included. As always, some popular alternatives to base R will also be suggested and many useful references provided for further reading.
