Geometry corresponds to the type of graphics ( histogram, box plot, line plot, density plot, dot plot, ….).It can also be used to control the color, the size or the shape of points, the height of bars, etc…. Aesthetics is used to indicate x and y variables.The principal components of every plot can be defined as follow: The gg in ggplot2 means Grammar of Graphics, a graphic concept which describes plots by using a “grammar”.Īccording to ggplot2 concept, a plot can be divided into different fundamental parts : Plot = data + Aesthetics + Geometry. Ggplot2 is a powerful and a flexible R package, implemented by Hadley Wickham, for producing elegant graphics. ![]()
