What is a Data Frame?
Let's move on to Data Frames. In general, the data frame in R is the same matrix allowing us to store values of different types. This aspect is the crucial difference.
Like in matrices, each element of the data frame has its 'address' among rows and columns. But unlike matrices, data frames must have names on their columns.
R provides us with tens of built-in datasets. Some can be represented as matrices (as they contain only numerical data), and some can be defined as data frames. Explore one of them by yourself!
