Repository Details

Interactively annotate ggplots

ggannotate

Lifecycle: experimental R build status Codecov test coverage CRAN status

{ggannotate} is a point-and-click tool to help you put your annotations exactly where you want them to go on your {ggplot2} plots.

The last step in data visualisation - adding annotations - is one of the most important, but it can be hard to get annotations in exactly the right place. With {ggannotate}, you interactively annotate ggplots using a Shiny-based RStudio add-in.

Installation

{ggannotate} is not yet on CRAN. It will be submitted to CRAN when it is more stable and feature-complete.

Install from GitHub:

remotes::install_github("mattcowgill/ggannotate")

Usage

Create a ggplot2 object, then call ggannotate():

library(ggplot2)
library(ggannotate)

p <- ggplot(mtcars, 
            aes(x = wt, y = mpg)) + 
  geom_point() 

ggannotate(p)

If you invoke ggannotate() without specifying a plot, it will use the last plot you modified or created, using ggplot2::last_plot():

ggplot(mtcars, 
            aes(x = wt, y = mpg)) + 
  geom_point() 

ggannotate()

You can also use the RStudio add-in to annotate your last_plot() with ggannotate().

Each of these options will launch a Shiny app. Add your annotation(s) and click โ€˜copy codeโ€™ to copy the annotation code to the clipboard. Then paste the copied code in your script and youโ€™re done!

You can adjust the size of the plot in the Shiny app so you can set it to be the same as your intended output.

Lifecycle

Lifecycle: experimental

{ggannotate} is still in active development, in an experimental phase. Aspects of the functionality are quite likely to change as the package evolves.

Suggestions are welcome (please file a GitHub issue). The UI will change substantially.
