## What it is
Radian is an alternative R console (REPL) with multiline editing, rich syntax highlighting, auto-completion, and shell/reticulate Python modes. It is a Python-based CLI tool often described as an IPython-like experience for R.

## Use cases
- interactive R console with syntax highlighting
- multiline editing in the R REPL
- auto-completion for R in the terminal
- run shell commands from the R console
- switch to a python repl via reticulate
- better terminal experience than the default R prompt

## When to choose
- you want a modern, feature-rich R REPL in the terminal
- you need multiline editing and syntax highlighting for R
- you want emacs/vi keybindings and bracketed paste in an R console
- you work with reticulate and want an integrated python repl mode

## When to avoid
- you need a tool under active development - radian is no longer actively developed (consider arf instead)
- you only need to run R scripts non-interactively
- you rely on RStudio or another GUI for interactive R work
