ggedit

We are pleased to announce the release of the ggedit package on CRAN.

To install the package you can call the standard R command

install.packages('ggedit')

The source version is still tracked on github, which has been reorganized to be easier to navigate.

To install the dev version:

devtools::install_github('metrumresearchgroup/ggedit')

What is ggedit?

ggedit is an R package that is used to facilitate ggplot formatting. With ggedit, R users of all experience levels can easily move from creating ggplots to refining aesthetic details, all while maintaining portability for further reproducible research and collaboration.
ggedit is run from an R console or as a reactive object in any Shiny application. The user inputs a ggplot object or a list of objects. The application populates Bootstrap modals with all of the elements found in each layer, scale, and theme of the ggplot objects. The user can then edit these elements and interact with the plot as changes occur. During editing, a comparison of the script is logged, which can be directly copied and shared. The application output is a nested list containing the edited layers, scales, and themes in both object and script form, so you can apply the edited objects independent of the original plot using regular ggplot2 grammar.
Why does it matter? ggedit promotes efficient collaboration. You can share your plots with team members to make formatting changes, and they can then send any objects they’ve edited back to you for implementation. No more email chains to change a circle to a triangle!

Updates in ggedit 0.2.0:

  • The layer modal (popups) elements have been reorganized for less clutter and easier navigation.
  • The S3 method written to plot and compare themes has been removed from the package, but can still be found on the repo, see plot.theme.

Deploying

  • call from the console: ggedit(p)
  • call from the addin toolbar: highlight script of a plot object on the source editor window of RStudio and run from toolbar.
  • call as part of Shiny: use the Shiny module syntax to call the ggEdit UI elements.
    • server: callModule(ggEdit,'pUI',obj=reactive(p))
    • ui: ggEditUI('pUI')
  • if you have installed the package you can see an example of a Shiny app by executing runApp(system.file('examples/shinyModule.R',package = 'ggedit'))

Outputs

ggedit returns a list containing 8 elements either to the global enviroment or as a reactive output in Shiny.

    • List containing updated ggplot objects
  • updatedLayers
    • For each plot a list of updated layers (ggproto) objects
