Precise axes, proper data transformation, and informative visual data mappings are critical components to any polished visualization. The scales package, the unsung hero behind ggplot2’s scale_* infrastructure, includes functions to help any R user manipulate and polish their visualizations. In this presentation, we will explore the functionality of this small but mighty package: demonstrating its functions for polishing guides, e.g. breaks and labels, managing data transformations, and for mapping aesthetic palettes to data.
