%description
The 'Rcpp' package provides R functions as well as C++ classes which offer
a seamless integration of R and C++. Many R data types and objects can be
mapped back and forth to C++ equivalents which facilitates both writing of
new code as well as easier integration of third-party libraries.
Documentation about 'Rcpp' is provided by several vignettes included in
this package, via the 'Rcpp Gallery' site at <https://gallery.rcpp.org>,
the paper by Eddelbuettel and Francois (2011,
<doi:10.18637/jss.v040.i08>), the book by Eddelbuettel (2013,
<doi:10.1007/978-1-4614-6868-4>) and the paper by Eddelbuettel and
Balamuta (2018, <doi:10.1080/00031305.2017.1375990>); see
'citation("Rcpp")' for details.
