I'd like to convert a data frame in a list with a specific format (minimal example ahead). For the following data frame, I' like to end up with a list of 5 elements which each have a list of 5 elements within themselves.
parameters = tidyr::expand(tibble(id=1:5, value = 1:5 * 2),id,value)
# A tibble: 6 x 2
id value
<int> <dbl>
1 1 2
2 1 4
3 1 6
4 1 8
5 1 10
6 2 2
result = base::split(parameters, list(parameters$id))
result = lapply(result, function(x) { x["id"] <- NULL; x })
so far it gets the id right (5 elements) but not the sub-elements within them. It gives for the first element
> a[1]
$`1`
# A tibble: 5 x 1
value
<dbl>
1 2
2 4
3 6
4 8
5 10
whereas I'd like to have it as in
> as.list(a$`1`$value)
[[1]]
[1] 2
[[2]]
[1] 4
[[3]]
[1] 6
[[4]]
[1] 8
[[5]]
[1] 10
such that the outcome looks something like this
[1]
[[1]]
[1] 2
[[2]]
[1] 4
[[3]]
[1] 6
[[4]]
[1] 8
[[5]]
[1] 10
[2]
[[1]]
[1] 2
[[2]]
[1] 4
[[3]]
[1] 6
[[4]]
[1] 8
[[5]]
[1] 10
Is there any elegant way to achieve this?
