When you are developing high-quality data visualizations using the industry-standard ggplot2 package within the R environment, achieving full transparency and context is paramount. Professional graphics must be entirely self-contained, meaning they should include all necessary supplementary information—such as data sources, methodological disclaimers, or copyright notices—without visually distracting from the primary plotted data. This is where […]
Mastering Scaling: The Introduction to the cex Family in R Plots When generating high-quality visualizations using the powerful base graphics system in R, achieving optimal clarity and impact relies heavily on the precise scaling of graphical components. The family of arguments revolving around cex (character expansion) provides the essential tools needed to fine-tune the relative
