Basic details of the ggplot2 package

At R Basics, our goal is to make it easy for you to find documentation about the ggplot2 package. That’s why we’ve compiled all the key information in one place. Dive into the details below to understand how this package can improve your work.

Title: Create Elegant Data Visualisations Using the Grammar of Graphics
Description: A system for 'declaratively' creating graphics, based on "The Grammar of Graphics". You provide the data, tell 'ggplot2' how to map variables to aesthetics, what graphical primitives to use, and it takes care of the details.

Technical details of the ggplot2 package

R documentation also provides technical details of a package, including its dependencies, enhancements, and compilation requirements. Learning this information will help you master the ggplot2 package.

Version: In R, a version refers to a specific release of a package and can be used to track changes. To find the version number of the ggplot2 package in the R console, you can use the packageVersion("ggplot2") function.
Compilation requirements: Some R packages include internal code that must be compiled for them to function correctly. The ggplot2 package does not have compilation requirements.
Required dependencies: A required dependency refers to another package that is essential for the functioning of the main package. The ggplot2 package has the following required dependencies: R (>= 3.3).
Suggested dependencies: A suggested dependency adds extra features to the main package, but the main package can work without it. The ggplot2 package has the following suggested dependencies: covr, dplyr, ggplot2movies, hexbin, Hmisc, knitr, lattice, mapproj, maps, multcomp, munsell, nlme, profvis, quantreg, ragg, RColorBrewer, rmarkdown, rpart, sf (>= 0.7-3), svglite (>= 1.2.0.9001), testthat (>= 3.1.2), vdiffr (>= 1.0.0), xml2.
External dependencies: External dependencies are other packages that the main package depends on for linking at compile time. The ggplot2 package does not use any external sources.
Imported packages: Importing packages allows developers to leverage existing code and functionalities without having to reinvent the wheel. The ggplot2 package has the following imported packages: cli, glue, grDevices, grid, gtable (>= 0.1.1), isoband, lifecycle (> 1.0.1), MASS, mgcv, rlang (>= 1.1.0), scales (>= 1.2.0), stats, tibble, vctrs (>= 0.5.0), withr (>= 2.5.0).
Enhancements: Enhancements help developers expand the capabilities of their packages without starting from scratch. The ggplot2 package has the following enhacements: sp.

Capabilities of the ggplot2 package

R documentation provides comprehensive information about a package, including its functions, datasets, and vignettes. Exploring this information will help you make the most of the ggplot2 package’s functionalities.

Functions: Functions play a crucial role in R packages. They allow you to perform specific tasks and computations efficiently. To identify the functions in the ggplot2 package, you can use the ls("package:ggplot2") function.
Datasets: Many R packages include built-in datasets that you can use to familiarize yourself with their functionalities. To identify any built-in datasets in the ggplot2 package, you can use the data(package = "ggplot2") function.
Vignettes: R vignettes are documents that include examples for using a package. To view the list of available vignettes you can use the vignette(package = "ggplot2") function. This code will display a list of available vignettes you can read.
Citation information: Citing R packages in your publications is important as it recognizes the contributions of the developers. To find the citation information for the ggplot2 package in the R console, you can use the citation("ggplot2") function.

Getting help with the ggplot2 package

If you have trouble using the ggplot2 package in R, there are several ways to get help.

The help() function: R’s built-in help system is a handy tool to find documentation. You can use the help("ggplot2") function to retrieve detailed information, examples, and usage instructions.
The ? operator: The ? operator is a shortcut for the help() function. You can simply type ?ggplot2 to quickly find documentation.
Discussion forums: Online forums are excellent platforms to ask questions, share knowledge, and troubleshoot issues. The most popular forums for R programmers are StackOverflow and Posit Community.
