F95在R中的有效调用:使用.Fortran还是。call ?

I am writing some R simulation code, but want to leverage Fortran's swift Linear Algebra libraries to replace the core iteration loops. So far I was looking primarily at the obvious option of using .Fortran to call linked F95 subroutines; I figured I should optimize memory use (I am passing very large arrays) and set I am writing some R simulation code, but want t
