10 - Subsetting Character Vectors I: Using Indices

In this tutorial, it's about time to dig a bit deeper into character vectors and answer the question:

• How do you retrieve values out of character vectors?

For answering this question, this video will focus on the first of the three different ways of subsetting a vector in R, namely by using the indexing of a character vector. The others will be presented in the next tutorials.
