[Rcpp-devel] [RCPP Sugar] sapply function

[Julien Duvanel]

Hello,  

Thanks for you quick answer (again!). After some research, I found the functions : Mapply_2, and Mapply_3. I'll have a look how it works.

I haven't understood the second proposition but if the first one works it's fine.

Have a nice evening,

J.
