How do I access vectors inside of another vector (or another array) in a way that I can save values inside it?
Example:
set <- c(a, b, c, d, e); while a, b, c, d, e are defined as vectors.
I want to access vector a, so I can save values in it and select it separately.
I have a loop in my script that practically does the same thing with different inputs and my intention is to save the output of each iteration in a different vector. Probably a rather basic problem, I'm quite new in R and so far I couldn't find a solution.
Hi and welcome! I think you might be looking for lists instead of vectors if you want to store multiple vectors in one object. Here's an example that creates a named list of 3 vectors and then you can use [] to access each of the list elements. If want to access a vector within a list you can use [[]].
a <- 1:5
b <- 6:10
c <- 11:15
set <- list(a = a, b = b, c = c)
set[1]
#> $a
#> [1] 1 2 3 4 5
set["b"]
#> $b
#> [1] 6 7 8 9 10
set[[3]]
#> [1] 11 12 13 14 15
