Visual Studio Code (with R Debugger Extension)

To set up R debugging in VS Code, you must install the R extension by Yuki Ueda and the R Language Server package in your R environment. You will also need to configure your `settings.json` file to point to your specific R installation path for the debugger to function properly. Once configured, you can set breakpoints directly in your R scripts.

Yes, by utilizing the `httpgd` R package or the built-in VS Code webview, you can view plots and inspect data frames directly in the editor. The R extension provides a modern interface that bridges the gap for users migrating from the traditional RStudio IDE. This allows for seamless, asynchronous rendering of complex graphics.

The R Debugger extension, which relies on the `.vscDebugger` package, fully supports setting breakpoints for line-by-line execution. This allows you to inspect your environment variables and evaluate expressions dynamically during a live R session. It provides an excellent graphical debugging experience that rivals the native tools in RStudio.

Migrating is relatively straightforward because VS Code can open the exact same `.R` and `.Rproj` files you already use in RStudio. While keyboard shortcuts differ out of the box, the R extension provides a comprehensive settings menu where you can remap keys to mimic the RStudio environment. This makes the transition much smoother for data scientists.
