**Cyrface - [http://www.ebi.ac.uk/saezrodriguez/cyrface/ webpage]**
**Cyrface** establishes an interface between **R** and **Cytoscape** by using different Java-R libraries, e.g. Rserve, RCaller. Cyrface can be used as a Cytoscape plug-in, e.g. to run R commands within Cytoscape, or used as a library to allow your plug-in to connect to R.
### Related Packages, Apps and Modules
Note that **Cyrface** works with **Cytoscape v2**. There is no **Cytoscape v3** app that allows callouts to **R** libraries. However, the [cyREST app](http://apps.cytoscape.org/apps/cyrest) does allow **R** applications (e.g., RStudio) to invoke **Cytoscape v3** services via the [RCy3 package](http://www.bioconductor.org/packages/release/bioc/html/RCy3.html).
Separately, the [RCyjs package](http://www.bioconductor.org/packages/release/bioc/html/RCyjs.html) can be used to display Cytoscape-like graphs in a web browser from within an R session.
