## Embedded R support

The [R project](https://www.r-project.org/) provides statistical computing and data vizualization.  SWISH can access R through [Rserve](https://rforge.net/Rserve/).  The *prototype* client for Rserve is available as the _pack_ [rserve_client](http://www.swi-prolog.org/pack/list?p=rserve_client).  The GitHub repository [rserve-sandbox](https://github.com/JanWielemaker/rserve-sandbox) provides the matching Rserve server as a [Docker](https://www.docker.com/) specification.

The notebooks below explain the basics of using R from SWISH.  You can test whether R is available from this server by running the query below.

  - [Exchanging R data frames](example/Rdataframe.swinb)
  - [Downloading (graphics) files](example/Rdownload.swinb)
