[R] cuhre usage ?? multidimensional integration

[R. Michael Weylandt]

Perhaps you should start by writing vectorized code; as it stands,
your code suggests you don't understand what simple operations like y
<- x actually do.

More to your question: what are cuhre  & crff ? They are not in base R
nor in any packages I have current loaded.
