R support

R is an integrated suite of software facilities for data manipulation, calculation and graphical display (http://www.r-project.org).

BioUML supports R script by R JavaScript host object.

R methods

•	local - return RObject for locally installed R application using Java R Interface (JRI API). It's the fastest way for using R.

Note: R_HOME environment variable should be set.

Example:

var rObject = R.local();

•	rserve - return RObject for locally installed R application using RServe service. This type of RObject is more stable and recommended to use with locally installed R application

Note: If RServe is not running the system will try to run it automatically, otherwise you should run it manually.

Example:

var rObject = R.rserve();

•	connect - return RObject for remote R installation. In this case R should be installed on BioUML server. This method have two string parameters:

host - address of BioUML server,

port - connection port

Example:

var rObject = R.connect("server.biouml.org", 80);
