Sorry, i just realized, that it output the sum of all vectors. I can work with this function but it would be much faster and easier if it would be possible to get the positions of evry match.
example: NA 1 NA 1 1 1 1 1 1 NA 1 rle returns lengths: int [1:6] 1 1 1 6 1 1 what i need would be something like, 1 1 1 3 3 3 3 1 1 but anyway i can work with rle, if there is no suitable function. thanks, Nico 2012/10/8 Mike Spam <ichmags...@googlemail.com>: > Hey Rui, > > Perfect!
