Dear Peter and Uwe

Thanks for your suggestions.
However,
> data[names(count),1,1] <- count[names(count)]
Still gives the indexing problem, guess because not all element of count can be found in data.

Found a way round this by
> temp<-rep(NA, times=as.numeric(names(count[length(count)])))
> temp[as.numeric(names(count))]<-count
> rwname<-rownames(data)
> for (i in 1:dim(data)[1]) data[i,1,1]<-temp[as.numeric(rwname[i])]
What works for me but I am convinced there is a far more elegant way.

Kind regards

Manuel

Well, you don't have a row named "names(count)" now do you? Try dropping the quotes.
