Re: [R] cuhre usage ?? multidimensional integration

I'm not quite familiar with R. Could you recommend some relative material. Actually, I'm not intend to loop from 1 to 1. I'm just trying to see if it works. It's supposed to be some len>1. I'm trying to solve the following example: there are 3 types of variables(x,w,t), they are not independen
