Rcpp sugar for rank function

c++, r, rcpp, syntactic-sugar

Solution

1) There is an `order` function here and `order(order(x))` is `rank(x, ties = "first")`.

2) A second way would be: `match(x, sort(x))`

ADDED Second approach.

Problem

I have been trying to get the rank of a vector in c++ using Rcpp. I have used other sugar functions like ``` is_na(); ``` Is there a similar sugar function for rank R function in c++. Also is there any list of available R sugar functions in Rcpp/
