How to analyse a Dataset in R Analysing a dataset in R typically involves several steps, such as loading the data, cleaning and preparing the data, exploring the data, and building models. Loading the data: The first step is to load the data into R, which can be done using functions like read.csv() or read.table(). …

How to work with Control Flow in R Control flow is the process of controlling the order in which a computer program executes its instructions. In R, control flow is used to make decisions and control the flow of execution of a program based on certain conditions. There are several control flow statements in R, …

Variables and Data Frames in R In statistical analysis, a variable is a characteristic or value that can change or take on different values. For example, a person’s age, height, or weight are all variables. In computer programming, a variable is a container for a value that can change during the execution of a program. …

Linear Regression in R using Partial Least Squared Regression Linear regression is a statistical method that helps to understand the relationship between a dependent variable and one or more independent variables. It is represented by an equation in the form of Y = a + bX, where Y is the dependent variable, X is the …
