[R-pkg-devel] CRAN submission - Specified C++11

[Ramon Diaz-Uriarte]

Dear Riccardo,

See, for example, here:  https://github.com/mlpack/mlpack/issues/3407


As explained there (https://github.com/mlpack/mlpack/issues/3407#issuecomment-1426249703) "R 4.1.0, the base of the current r-oldrel (aka "previous release") already defaulted to C++14."


So, unless you really need C++11 and cannot use newer standards, you can probably remove

CXX_STD = CXX11


Best,

R.
