I am asking this question because String comparison in R seems to be awfully slow (based on profiling results) and I wonder if perhaps '==' alone is not the best one can do. I did not ask for anything particular and I don't think I need to provide a self-contained source example for the question. So, to re-phrase my question, are there more (runtime) effective ways to find out if two strings (about 100-150 characters long) are equal?
