This is a class to get ROOT's objects from R's objects

TRObject class

The TRObject class lets you obtain ROOT's objects from R's objects.
It has some basic template opetarors to convert R's objects into ROOT's datatypes

A simple example

#include<TRInterface.h>
void Proxy()
{
ROOT::R::TRInterface &r=ROOT::R::TRInterface::Instance();
ROOT::R::TRObject obj;
obj=r.Eval("seq(1,10)");
TVectorD v=obj;
v.Print();
}

Output

Vector (10)  is as follows
|        1  |
------------------
|1
|2
|3
|4
|5
|6
|7
|8
|9
|10
