# Working With Vectors

In this lesson, you will build what you've learned in this Introduction to R course by learning how to index, manipulate, and perform calculations on vectors in R.

In addition, you will get a more in-depth look at manipulating vectors for data analysis by working with a subset of values in a vector, assigning names to elements of a vector, and using comparison operators to answer questions about data stored in vectors.

After completing this lesson about vectors, you will be able to explain vector recycling, a super important concept in R, and identify the three different data types in R: numeric, character, and logical.

After you finish this lesson, you will be well-equipped to start building simple programs in R; what you build is limited by the depth of your imagination. If you have trouble coming up with ideas, you can practice by following this tutorial to build a simple calculator and maybe some additional ideas for programs will come to mind.
