[Rcpp-devel] Problem with RCPP Paralell

[Kevin Ushey]

Hi Roberto,

(RcppParallel maintainer here.) We had some correspondence with
Professor Ripley regarding this; package authors affected by this
could request the C++14 standard in their package as described here:

https://cran.r-project.org/doc/manuals/R-exts.html#Using-C_002b_002b-code

I believe it should suffice to include:

CXX_STD = CXX14

in your package's `src/Makevars`.

That said, I'll see about submitting a patched version of RcppParallel
so that package authors won't need to contend with these issues.

Best,
Kevin
