-- Octave (using oct2py)
-- SQL (using jupysql with DuckDB)
-- SAS (requires licensed copy and a way to access it)
+- R (using [`{rpy2}`][rpy2magic])

+- Octave (using [`{oct2py}`][oct2pymagic])
+- SQL (using [`{jupysql}`][jupysqlmagic])
+- SAS (using [`{saspy}`][saspymagic] + licensed copy and a way to access it)
 
 Additional languages are supported via magic commands without requiring specific setup cells.
