Attributing values to matrix according to names

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

works but

data["names(count)",1,1]<-count["names(count)"]

Fails with Error: indexing outside limits.

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