How to visualise correlation in R Visualizing correlation in R is an important step in understanding the relationship between different variables in a dataset. Correlation can be positive, negative or zero. Positive correlation means that as one variable increases, the other variable also increases. Negative correlation means that as one variable increases, the other variable …
How to visualise Dataset in R Visualizing a dataset in R is an important step in understanding the underlying patterns and relationships in the data. There are various data visualization techniques and packages available in R, such as ggplot2, lattice, and base R plotting functions. Some of the most commonly used visualizations in R include: …
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. …
