An updated version of the corels package is now on CRAN! The ‘Certifiably Optimal RulE ListS (Corels)’ learner provides interpretable decision rules with an optimality guarantee—a nice feature which sets it apart in machine learning. You can learn more about corels at its UBC site.
This released fixes an issue discovered on one of the test machines
used by Brian Ripley. If and when C compiler flags are set locally that
are in fact upsetting the C++ compiler, then the build fails. While not
an issue for years and not reproducible on (vanilla) Debian, Ubuntu or
Fedora machines it does indeed balk at his end as e.g. the flag
-Werror=implicit-function-declaration he sets for C is
incompatible with the current C++ compiler. The fault was our:
CFLAGS was passed on to PKG_CXXFLAGS letting C
options seep into C++ deployment. This has been corrected: we only deal
in C++ flags now.
Courtesy of my CRANberries, there is also a diffstat report for this release.
