Dear all, I have a (small) vector "r" containing values and a (large) vector "index" containing indices. Is there an easy way to select the elements of "r" that are indexed by "index"? I.e., is there a way to reproduce the following R code with Rcpp (without using loops)? r <- c(1,11,111) index <- c(2,2,1) r[index] Thanks in advance, /g
