...isin". This can easily be done by a loop: > loop <- poids2 > for(i in 1:6){ + loop[i,voisin[i,]] <- wei2[i,] + } But I expect it to be quite slow with my larger dataset. Does any of you has an idea how I could remove the loop and speed up the operation? Best regards, Bastien Ferland-Raymond, M.Sc. Stat., M.Sc. Biol.

DearR Users, I have a problem which I think you might be able to help. I have a dataframe which I'm trying to "filter" following different groups I specified.

I have posted this question to the netfilter mailing list along with #ebtables, #iptables, and #netfilter. Nobody has really responded, so I''m led to believe that it is either incredibly complicated or *really* simple. Please, somebody throw me a bone here! Ok, on with the show... I have a bridge (br0) with two interfaces (eth1 and eth2). Neither br0, eth1, or eth2 have an

Hi all, I''ve not been able to find an explanation of the relationship between prio and rate as they apply to the HTB technique. Hopefully someone on here will be able to help me.
