Box Plots
A box plot is a type of graph that displays the distribution of a numerical variable. It is useful for identifying the median, quartiles, and outliers in data sets.
R
# create a box plot of the horsepower # variable in the mtcars data boxplot(mtcars$hp, xlab = "Horsepower", main = "Box plot of horsepower") |
Output:
Box plot for Graphical Data Analysis
This creates a box plot of the horsepower variable in the mtcars data set. The xlab and main arguments specify the labels for the x-axis and the main title, respectively.
Graphical Data Analysis in R
Graphical Data Analysis (GDA) is a powerful tool that helps us to visualize and explore complex data sets. R is a popular programming language for GDA as it has a wide range of built-in functions for producing high-quality visualizations. In this article, we will explore some of the most commonly used GDA techniques in the R Programming Language.
For the data visualization, we will be using the mtcars dataset which is a built-in dataset in R that contains measurements on 11 different attributes for 32 different cars.
