Matrices
In the first section, you will learn the two-dimensional structure that is widely used in math. In R, this data type is used not only for math purposes but also has many real-life purposes.
What is a Matrix?
matrix() Function
Transposing
Matrix Indexation
Namings
Operation with Matrices
Challenge
Data Frames
In the second section, you will learn data frames - an 'upgraded' version of the matrix. Unlike matrix, the data frame may contain data of different types. Most real-life tables can be represented as data frames. You will learn how to create/manipulate data frames and extract necessary data.
What is a Data Frame?
data.frame() Function
Columns Accessors
Logical Indexing
Manipulating Columns
Manipulating Rows
Challenge
Lists
In the final section, you will learn the lists in R. This data type works as vectors but may contain data of different types.
What is a List?
Namings
Extracting List Elements
