每次当我使用RcppEigen或RcppNumerical时，我都会在控制台中获得一条很长的警告信息 .
/home/Haache/R/x86_64-pc-linux-gnu-library/3.4/RcppEigen/include/Eigen/src/Core/util/XprHelper.h:170:83: warning: ignoring attributes on template argument ‘Eigen::internal::packet_traits<double>::type {aka __vector(2) double}’ [-Wignored-attributes]

但是，代码运行良好 . 我为任何代码获取此代码 . 加载后会出现警告
#include <RcppEigen.h>
要么
#include <RcppNumerical.h>
我的所有包裹都是最新的

正如Dirk在评论中所说，您可以将
-Wno-ignored-attributes添加到编译器标志中 . 您可以通过创建文件~/.R/Makevars并添加来实现
