|== | 3% | Vectors come in two different flavors: atomic vectors and lists. An atomic | vector contains exactly one data type, whereas a list may contain multiple | data types. We'll explore atomic vectors further before we get to lists.
...
|==== | 5% | In previous lessons, we dealt entirely with numeric vectors, which are one | type of atomic vector. Other types of atomic vectors include logical, | character, integer, and complex. In this lesson, we'll take a closer look at | logical and character vectors.
