{ggannotate} makes it easy to add annotations to your {ggplot2} plots by pointing and clicking.
Annotations are often the most important part of a data visualisation, but getting them in exactly the right place can be fiddly.
{ggannotate} launches an interactive Shiny gadget that lets you click on your plot to place annotations exactly where you want them. It then generates the code to reproduce your annotations
Features
- Add text, labels, curves, and rectangles to any ggplot2 plot
- Place multiple annotations in a single session
- Full support for faceted plots
- Annotations using the same geom are combined into a single layer for cleaner code
- Copy generated code to the clipboard with one click
- Use as an RStudio addin or call directly from the console
Installation
Install the development version from GitHub:
# install.packages("pak")
pak::pak("MattCowgill/ggannotate")Usage
Firs, create a ggplot2 object:
library(ggplot2)
library(ggannotate)
ggplot(mtcars, aes(x = wt, y = mpg)) +
geom_point()Then just call ggannotate() or use the handy RStudio addin to invoke ggannotate.
It also works with named plots:
p <- ggplot(mtcars, aes(x = wt, y = mpg)) +
geom_point()
ggannotate(p)This launches a Shiny app where you can add your annotations interactively. When you’re done, click “Copy code” to copy the annotation code to your clipboard, then paste it into your script.
