A new release of
Rcpp
awaits inclusion on
CRAN and has also
been sent as a .deb to
Debian. It will
hit mirrors over the next few days, in the meantime you can get it
here as well.
This release has a couple new features :
- inline support: the
cfunction from Oleg Sklyar's excellent
inline package
has been imported and adapted. This means simple C++ programs can be defined in an R character
vector and passed to cfunction which will create a complete file that it then
compiles, links and loads --- giving you access to compiled C++ code right from the R prompt
without having to worry about compiler flags, linker options, ... Better still, we extended
this to not only support Rcpp but
any external library via addtional header / linker arguments that will be passed to R via
the PKG_CPPFLAGS, PKG_CXXFLAGS and PKG_LIBS environment
variables.
- this even works on Windoze (if you have the Rtools installed as detailed in the Windows Toolset appendix to the R
Installation manual) in exactly the same way. And no folks, that still does NOT mean you can use Visual Whatever -- R
really requires MinGW as the links in this parapgraph document very plainly. But if and when you have the
tools, R's remarkable consistency across operating systems allows you to use Rcpp and inline in pretty much the same way.
- A handful of new examples for the inline support have been added.
- A new type
RcppSexp for simple int, double or std::string scalars as well as vectors; this is particularly
useful for the inline support.
- This also completes the source code reorginsation: every class now has its own
header and implementation file
- Last but not least, the package has been relicensed from LGPL-2.1 (or later) to GPL 2 (or later).
Fuller details are in the ChangeLog on
Rcpp page.
