ggplot2 - Create Elegant Data Visualisations Using the Grammar …
It describes the theoretical underpinnings of ggplot2 and shows you how all the pieces fit together. This book helps you understand the theory that underpins ggplot2, and will help you create …
Introduction to ggplot2
ggplot2 is an R package for producing visualizations of data. Unlike many graphics packages, ggplot2 uses a conceptual framework based on the grammar of graphics. This allows you to …
Package index • ggplot2
To create your own geoms, stats, scales, and facets, you’ll need to learn a bit about the object oriented system that ggplot2 uses. Start by reading vignette("extending-ggplot2") then consult …
Create a new ggplot — ggplot • ggplot2
ggplot() initializes a ggplot object. It can be used to declare the input data frame for a graphic and to specify the set of plot aesthetics intended to be common throughout all subsequent layers …
Aesthetic specifications • ggplot2
Typically you specify font size using points (or pt for short), where 1 pt = 0.35mm. In geom_text() and geom_label(), you can set size.unit = "pt" to use points instead of millimeters. In addition, …
Bar charts — geom_bar • ggplot2
Thus, ggplot2 will by default try to guess which orientation the layer should have. Under rare circumstances, the orientation is ambiguous and guessing may fail. In that case the orientation …
A box and whiskers plot (in the style of Tukey) — geom_boxplot • …
Thus, ggplot2 will by default try to guess which orientation the layer should have. Under rare circumstances, the orientation is ambiguous and guessing may fail. In that case the orientation …
Layer position adjustments — layer_positions • ggplot2
In ggplot2, a plot is constructed by adding layers to it. In addition to geoms and stats, position adjustments are the third required part of a layer. The 'position' part of a layer is responsible …
Violin plot — geom_violin • ggplot2
Thus, ggplot2 will by default try to guess which orientation the layer should have. Under rare circumstances, the orientation is ambiguous and guessing may fail. In that case the orientation …
