Marco, do you actually use R? If yes, see ?setdiff.
setdiff is an R function, it is the difference operation between
two sets, it calculates the elements that are in the first set,
but not in the second. Maybe there is something similar in Python,
but you'll have to write it for yourself if you use C. It is not
hard, just sort both vectors and go over them once to keep the elements
that are in the first vector only. As always, using a higher level
language is easier.
Best,
Gabor
