How can I generate and name 10,000 vectors automatically in R programming?

Question

I have a vector that has 10,000 elements(natural numbers). The vector is, say, End.Num. I want to generate and name 10,000 new vectors using this vector as below.

NewVec1 <- 1:End.Num[1]
NewVec2 <- 1:End.Num[2]
NewVec3 <- 1:End.Num[3]

NewVec9999 <- 1:End.Num[9999]
NewVec10000 <- 1:End.Num[10000]

How can I this without writing 10,000 lines in R? Thanks for your attention.

Answer 1

Try this:

1. Define a function

   vec <- function(x) {
     v <- 1:x
   }
   

2. Generate a list of vectors

   the_list <- lapply(End.Num, FUN = vec)
   

3. Split the_list in n variables

   list2env(setNames(the_list,paste0("v",seq_along(the_list))), envir = parent.frame())
   

I advise you to stop at point 2 and to access the elements of the list via the_list[[i]].
