RStudio

RStudio is the premier integrated development environment for the R statistical programming language. It is available in open source and commercial editions and runs on the desktop (Mac, Linux, and Windows) or over the web with RStudio Server.

Python and Notebooks

• Use a shared Python session to execute Python chunks via reticulate
• Simple bindings to access R objects from Python chunks and vice versa
• Show matplotlib plots emitted by Python chunks

Keyring

• Store passwords and secrets securely with keyring by calling rstudioapi::askForSecret()
• Install keyring directly from dialog prompt

D3

• Author D3 visualizations in RStudio and preview in the Viewer pane
• Use r2d3 D3 visualizations in R Notebook chunks

Jobs

• Run any R script as a background job in a clean R session
• Monitor progress and see script output in real time
• Optionally give jobs your global environment when started, and export values back when complete

SQL

• Author SQL queries in RStudio and preview in the SQL Results pane

Testing

• Run Tests command in testthat R scripts for direct running
• testthat output in the Build pane with navigable issue list
• Integration with shinytest to record and run Shiny app tests

PowerPoint

• Create PowerPoint presentations with R Markdown

Package Management

• Specify a primary CRAN URL and secondary CRAN repos from the package preferences pane.
• Link to a package’s primary CRAN page from the packages pane.
• Configure CRAN repos with a repos.conf configuration file and the r-cran-repos-file option.
• Suggest additional secondary CRAN repos with the r-cran-repos-url option.

Plumber

• Create Plumber APIs in RStudio
• Execute Plumber APIs within RStudio to view Swagger documentation and make test calls to the APIs
• Publish Plumber APIs to RStudio Connect
