Thanks for your answers.
Now it works both as package and with sourceCpp.

Hi Petre,
It sounds like what you want is to curry a function f(x, a) into a function
g(x) that will then get passed to your root-finder. See:

I don't know how to change the parameters of the function. The Brent

If you really want to use the module as an object, you have to pick it up from
the right spot:

The BH package -- which provides a solid subset of Boost in a header-only
package for use by R, with or even without Rcpp.
I had gotten a recent email pointing out that a noise compiler warning was
indeed a bug in (upstream) Boost 1.51.0 which has been fixed. I have moved
to 1.54.0 -- and this i

This may not work from command-line use.

consider that. Your example is pretty th

Shame that it had to come to this, but apparently Rcpp-devel is only for
discussing the Dirk approved implementation of Rcpp.

And another 2 cents from me.
A package is the basic unit of functionality in R. Whatever
functionality you are providing, I think a package is the best way to
deliver it. There is a well developed framework for versioning,
dependency resolution, testing, and distribution.

Hello,
I want to expose a C++ class to R through Rcpp. For that I want to try
out a few examples from the note "Exposing C++ functions and classes
with Rcpp modules" and the book "Seamless R and C++ Integration with
Rpp". But I can't manage to get them work. It ends up with an error.
So this
