Hi
I will not answer your question directly but instead I have some recommendation
for you. If you can put these data frames to one list object when you creates
them, you can save yourself a lot of troubles.
some.list<-vector("list", n)
for (i in 1:n) {
some.list[[i]] <- some extensive computation or reading files
}
then you can use lapply/sapply/for cycle to make any computation directly on
list.
I use R for more than 10 years and I do not remember any situation when I would
need to create multiple objects in "n1":"nx" naming manner.
