Hi same result can be achieved by
dat.ag<-aggregate(dat[ , c("DCE","DP")], by= list(dat$first.Name, dat$Name, dat$Department) , "I") Sorting according to the first row seems to be quite tricky. You could probably get closer by using some combination of split and order and arranging back chunks of data ooo1<-order(split(dat$DCE,interaction(dat$first.Name, dat$Name, dat$Department, drop=T))[[1]]) data.frame(sapply(split(dat$DCE,interaction(dat$first.Name, dat$Name, dat$Department, drop=T)), rbind))[ooo1,] Ancient.Nation.QLH Amish.Wives.TAS Auction.Videos.YME 2 0.28 NA NA 4 0.28 NA NA 1 0.54 0.59 0.57 3 0.54 0.59 0.57 however I wonder why the order according to the first row is necessary if all NAs are on correct positions?
