R help - Sep 2012 - combing list objects

Hi,
I am trying to combine a long list but I can't work out how to do it, for
example:

abun<-list(rep(0,5),rep(0,7),rep(0,4),rep(0,10))
nb<-c(5,5,1,8)

fill.abun <- function(x, y) {
        set <- sample(1:length(x), size = y)
        x[set] <- rlnorm(length(set))
        return(x)
    }
            
abun <- mapply(fill.abun, abun, nb)
abun

## I want all the data in one list or column which I can extract to a
dataframe or matrix
## the best I have come up with is:

abun2<-c(abun[[1]],abun[[2]],abun[[3]],abun[[4]])

## but I will have a lot more data and so this is not feasible

Thanks,
Chris

Hello,

Try ?unlist.
unlist(abun)

Hope this helps,
