In this R video tutorial we will learn to Create, Modify and Work with Vectors and Matrices in R.

▶︎▶︎Reminder: One of the important features of R is that it can handle complex statistical operations in an easy and efficient way. R handles complex computations using Vectors, Matrices, Lists, Dataframes and Datasets; In this video we focus on Vectors and Matrices in R. In R, Vector is a basic data structure that contains element of similar type (logical, integer, double, character, complex or raw). A matrix is basically a two-way generalization of a vector. Instead of a single index, we can use two indexes, one representing a row and the second representing a column.

▶︎▶︎In this R tutorial you will learn:
▶︎ How to create vectors in R for numbers or objects using the c function or concatenate function
▶︎ How to use seq function to create sequence data in R
▶︎ How to use rep function in R to create a vector of repeated numbers or characters
▶︎ How to create a matrix using matrix function in R and use square brackets to extract certain elements from a matrix in R
▶︎ How to perform basic arithmetic functions on the elements of one vector, preform arithmetic functions on the corresponding elements of two vectors and perform element-wise arithmetic functions in a matrix in R Statistical software.

This video is a tutorial for programming in R Statistical Software for beginners.
