Restart R now closes the webR worker, which stops R even in the middle of an endless loop, and boots a fresh one in the same page. The per-instance caches (session setup, installed packages, restored uploads) reset, and the page content remounts so lessons and the R Workspace pick up the new R. Drafts and scripts are kept.

Before: "Restart R" (and "Try again" after a failed start) reloaded the whole page.
After: it stops R, even in the middle of an endless loop, and starts a fresh R in the same page. Lessons and the R Workspace pick up the new R, and drafts and scripts are kept.
How:
restartR()closes the webR worker and tells listeners; the session setup, package and upload caches reset, and App remounts the page content and boots again. Checked with real R in a local browser:while (TRUE) {}in a lesson block and in the Workspace, then Restart R, then new code runs on a fresh R with no page reload.Generated by Claude Code
