Namings | Lists
R Introduction: Part II

# Namings

In the previous chapter, you saw that list output contains indices within double square brackets. That's good, but wouldn't it be better if we had names instead of indices? Indeed, it would.

There are two ways to set names on list elements. The first is used in the process of list creation. Within `list()` function use `name = values` equalities (name should be used without quotes). For example, let's rewrite the previous example with names.

That's much better! The second way is to set names for the already created list. Assign a vector of names to `names(list)` function. For example,

Завдання

Given the list `info` from the previous chapter. Using the second method (`names()` function), assign the following names to elements: `'Course name', 'Section', 'Chapter', 'Chapter overall'`. Output the list, then.
