...Cs(a,b,b,c,a,b) site <- c(1,1,4,4,1,4) mat1 <- cbind(cata, catb, doga, dogb, rata, ratb, bata, batb) Df <- data.frame(site, id, mat1) nn <- levels(Df$id) Df nn rate <- c(2,3,4) for (i in 1: length(nn)) { dd<- subset(Df, id==nn[i]) scat <- sum(c(dd$cata,dd$catb), na.rm=T) sdog <- sum(c(dd$doga,dd$dogb), na.rm=T) srat <- sum(c(dd$rata, dd$ratb), na.rm=T) sbat <- sum(c(dd$bata,dd$batb), na.rm=T) sss <- c(scat,sdog, srat,sbat) * rate[i] print(sss) }

I want to calculate the "scat" etc, values for each level of id, output a vector of these values that is a <- c(scat, sdog, srat, sbat ) and do an rbind on them. Each level of id has a different value of rate. So far it it looks to me like I can do this by a series of repeated subsets of Df butI would think that I should be able to do this with a function but I am not having any luck. Thus far, I'm not even...

Hi all, Since it looks like I''ll be attending FOSDEM, I now need to find some lodging, and if possible I''d like to line up a presentation or four. Someone in the community offered to let me crash with them if I came to the conference (someone with the nick of ''robk'' on IRC, I think), so I''d like to take that person up on it if possible.
