Side-by-side plots with ggplot2

Side-by-Side Plots with ggplot2: Easy Solutions for Common Issues 😎📊

Have you ever wanted to showcase two plots side by side with the same scale using the powerful ggplot2 package? If so, you're in the right place! In this blog post, we'll dive into the world of side-by-side plots and provide you with easy solutions to common issues you may encounter. So, let's get started! 🚀

The Challenge: Combining Plots Side by Side 🤔

To illustrate the problem at hand, let's take a look at this example code snippet:

x <- rnorm(100)
eps <- rnorm(100, 0, 0.2)
qplot(x, 3*x+eps)
qplot(x, 2*x+eps)

In this code, two plots are being created using the qplot function. However, by default, they are shown sequentially, not side by side. Our challenge is to visually present these plots next to each other with the same scale. How can we accomplish this? Let's find out! 💪

Solution 1: Using grid.arrange from the gridExtra Package 📊

One intuitive solution is to utilize the grid.arrange function from the gridExtra package. First, make sure you have the package installed by running install.packages("gridExtra"). Then, include the following code snippet to get the desired side-by-side plots:

library(gridExtra)

plot1 <- qplot(x, 3*x+eps)
plot2 <- qplot(x, 2*x+eps)

grid.arrange(plot1, plot2, nrow = 1)

By incorporating the grid.arrange function, we can combine both plots into a single grid, displaying them side by side. The nrow = 1 argument specifies that we want to put the plots in a single row. Feel free to experiment with nrow and ncol options to suit your specific layout preferences. 🎨

Solution 2: Using patchwork for Easy Composition 🖼️

Another fantastic solution is to leverage the patchwork package, which provides a simple way to compose multiple plots together. If you don't have the package installed, you can get it by running install.packages("patchwork"). Once installed, try out this code snippet:

library(ggplot2)
library(patchwork)

plot1 <- qplot(x, 3*x+eps)
plot2 <- qplot(x, 2*x+eps)

plot1 + plot2

By using the + operator, we can easily combine the plots in a side-by-side manner. The patchwork package makes the composition process a breeze, enabling us to create intricate plot arrangements with simplicity. 🎭

Additional Tips and Tricks 👍

• Remember, you don't necessarily need to put the plots in the same data frame to achieve side-by-side display. The approaches we discussed allow you to combine independent plots effortlessly.

• Feel free to experiment with different arguments and options for the functions we mentioned. You can adjust the layout, titles, axis labels, and more to suit your specific needs and create visually stunning side-by-side plots.

Time to Show Off Your Side-by-Side Plots! 🎉

Now that you have learned two straightforward solutions to showcase side-by-side plots with ggplot2, it's time to put your knowledge into practice! Combine your plots side by side, create amazing visualizations, and share your results with the world.
