[R] help needed on RcppEigen....

I am using R to model stock prices but a slow "for" loop has stifled my research.
I am using Rcpp to speed up my "for" loop. I am also using RcppEigen to implement block operations on xts objects.....
how do I use RcppEigen? If I just load it by:
it is not recognising the .block method in C++.
If I include it inside the cppFunction:
> cppFunction(' include <RcppEigen.h> .....body')
I get the following error:
> error: "include doesn't name a type"
My question is : how do I manipulate the installed RcppEigen package for the cppFunction to recognize block operations that are part of the Eigen library in C++? If I have to use the "include" key word (something like this: include <RcppEigen.h> ), where exactly should i position it in order to work with cppFunction ( I want to use Eigen block operation methods or functions inside the body of the cppFunction)?
very many thanks for your time and effort.....
