idx <- sort(unique(strtrim(names(nr.genes), 4))) new <- nr.genes.names[match(strtrim(names(nr.genes), 4), idx)] names(nr.genes) <- new This code will correctly map the old names to their corresponding positions in the idx vector, which is sorted and contains only the relevant part of each name. The new names are then assigned to nr.genes.
