@JLC You're very welcome. Another thing you may want to consider is to post your code on Code Review. Since you have a working and reproducible piece of code, you may want to ask there for possible code optimisations. They've got an R code tag as well:-) — Maurits Evers 17 secs ago
Welcome to stack overflow, Vincent. Concerning your second question about advice in general. SO has a section on Code Review. I recommend posting this question there as well. You will get some really great advice on how to clean it up. This isn't really the area for that. — SteveJ 10 secs ago

the only thing missing to be complete is the treatment of m, t and i, as far as I can see. In order to add that, you don't really need to know what you are doing. Do you also know what remark would be given during a code review? — Stultuske 43 secs ago

@SᴀᴍOnᴇᴌᴀ I would indeed - and feel free to disagree with me and roll it back anyway (that intervention wouldn't be contrary to site rules about answer-invalidating edits), but I believe the way the edit was made (with the seams showing, i.e. it's explicitly called out), with the instruction being commented-out rather than outright removed, keeps the little DoEvents side-note relevant. IMO the Q+A as a whole remains coherent, so while it's technically invalidating, the spirit of the rule is upheld, there are far worse cases of answer invalidation edits that do warrant a rollback ;-) — Mathieu Guindon 1 min ago
