In this tutorial, we will learn how to use cbind() function in R. The cbind() function in the R programming language is used to combine vectors, matrices, or data frames by columns. cbind() stands for column bind as it combines by column. The basic syntax for using cbind() is as follows: Here, x and y… Continue reading How to use cbind() function in R
How to use outer function in R
In this tutorial, we will learn how to use outer() function in R. The outer() function in R is a useful tool for applying a function to all pairs of elements of two input vectors. The basic syntax of using outer() function is this Here X and Y are vectors and default function to the… Continue reading How to use outer function in R
How to use dollar $ operator in R
R programming language uses $ operator (dollar operator) for extracting or accessing elements from data structures like list or dataframe. For example, with $ operator we can select specific elements of a list or dataframe by their names instead of their position. In this post, we will learn two most common uses of $ operator… Continue reading How to use dollar $ operator in R
How to compute mean in R
In this tutorial, we will learn how to use mean() function in R to compute mean (or average) of a vector. In the most basic use case, mean() function takes a vector as input argument and computes arithmetic mean of the elements in the vector In R, we can learn more about the function with… Continue reading How to compute mean in R
How to calculate cumulative sum in R
In this tutorial, we will learn how to calculate cumulative sum in R. With cumsum() function in base R, we. can compute cumulative sum of a vector in R. We will first see two examples of using cumsum() on a vector to compute cumulative sum and then we will compute cumulative sum of a column… Continue reading How to calculate cumulative sum in R
