Density Plots
A density plot is a type of graph that displays the distribution of a numerical variable as a smooth curve. It is useful for identifying the shape, spread, and skewness of data sets.
R
# create a density plot of the # displacement variable in the mtcars data plot ( density (mtcars$disp)) |
Output:
This creates a density plot of the displacement variable in the mtcars data set.
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.
