Yes of course. 

As R in a C program, and as .C (no SEXP) and .Call (SEXP interface) are C
interfaces, Rcpp and Rcpp11 are in the exact same boat.  

There is no advantage at the interface level. Everything turns to C the
moment we interface R.  Beyond that point, we can use C++ in all its
features, including C++11.  Rcpp has supported the option of C++11 as long as
the compilers have as it required just an optional switch.

Earlier this week we passes a new milestone: there are now 200 packages on
CRAN which use Rcpp.  And with the BioConductor 2.14 release, there are now
another 27 packages in BioConductor.

This is a very humbling number, and we are very happy that Rcpp is finding
such wide, and rapidly growing, use.  

Speaking for the Rcpp Core team, we will try our best to maintain (and
extend) the interface and functionality provided by the package for your use
in "Programming with Data" (to quote John's wonderful book title).  R and C++
make a fantastic combination for that, and we are so glad our interface layer
and tool is finding such wide and growing use.

Hi, all
I am new to Rcpp and might need some of your help, thanks a lot.
I was trying to compile my Rcpp program in eclipse. But I met a lot of
errors when I was trying to do so. Most of the error comes from the
String.h. Here is the command and part of error:

You have not shown a reproducible error in Rcpp. What you have shown is that
you failed to build something using Eclipse.  Which may be well a setup error
on your part.

We support an R package which is fairly rigorously tested and which supports
'R CMD INSTALL .....' for various values of '.....' (and various different
incantations, including RStudio which tries hard (and successfully) to behave
just like R by invoking R as R).

For everything else, you are mostly on your own. Windows is twice as hard
because of its inconsistent $PATH etc. 

I would try to build something simple first, either directly with R or via
RStudio, so that you know that the code works, and then migrate a known
working setup to your chosen environment.

Good luck,  Dirk
