The ggplot2 library is a follow-up of the ggplot library, and stands for the ‘grammar of graphics’. It produces attractive, professional-looking graphics that are good, especially for presentations. This comes at a cost of some of the flexibility that standard R graphics give, but it is often worthwhile.

Example : First-Degree Polynomial - Equation of a Line Graph the relationship between x and y for y = f(x) = 3x + 6 in the x-range of -10 to 10. Solution: A first-degree polynomial is the equation of a line. To draw the line, find two points of the line and join them. ...

And while the ggplot2 package does have one or two quirky display outputs, it is also extremely forgiving. Instead of using the default x-axis line, I'll replace it with a makeshift horizontal line using the geom_hline function. # Make final adjustments to the plot in R. # Override previous specifications for x axis line.

This tutorial is going to take us through the process of creating the Cleveland Dot Plot with R. Stephanie's original graph is below. Quick Notes! We'll be using the ggplot2 package to complete this visualization within R. A third-party graphics program will also be used to finalize the multicolor title.

You’ll notice we’ve added another aesthetic to the graph- errorbars! There are many circumstances in which a boxplot can obscure differences between groups, because of how much data it plots all at once. Mean + errorbars can be a nice, simple solution to showing differences between groups, if they exist.

Graphically, a function . f ( x ) is convex if a line segment joining any two points [ x 1 , f ( x 1 )] , [ x 2 , f ( x 2 )] , of f ( x ) lies on or above the surface of f ( x ) (see the graph below.)An easier way to show that a function is convex is to use the second order derivative of the function, if …

>library(ggplot2) Now, you can use the super cool functions in the ggplot2 package that will make you look like a rockstar. Graphics. Graphics functions in R come in three types: High level functions. High level functions generate new graphics, like a boxlot, scatterplot, bar graph, or pie graph.

The first step in creating a ggplot2 graph is to define a ggplot object. We do this with the function ggplot, which initializes the graph. If we read the help file for this function, we see that the first argument is used to specify what data is associated with this object:
