I have a question that should be quite simple, but I can’t figure out how to do it. I would like to filter a list in such a way that I only keep sublists of a certain length (say 1, or 2).
Say I have a list ((6000) (6000) (6400 6700) (6400 6700) (6000) (6000) (6400 6700) (6400 6700)), and I want to end up with ((6400 6700) (6400 6700) (6400 6700) (6400 6700)).
I suspect I’m going to have to dig into omif, or mapcar, but if there’s a simple way to do this, I would appreciate a pointer. (Better yet, if it could be done on the object level, I thought there was tool for that in OMTristan, but I was mistaken).
Thanks in advance!
