Don't do that. As Jim suggested use list inside a loop. #declare a list lll<-vector("list",3) #do your loop for(i in 1:3) lll[[i]] <- letters[i] lll [[1]] [1] "a" [[2]] [1] "b" [[3]] [1] "c" But I feel that you could maybe achieve desired result without loop in more Rish way. If what you want to do is reasonable and frequent I believe somebody already made a function which does what you want.
