How to Split a List in R ?

Answer

To split a list in R, you can use the split function or create sublists manually using list manipulation.

✐ Examples

1 Split a List Using split

In this example,

We create a vector named numbers with initial integer values.
We use the split function to split the vector into groups based on a factor.
The split function returns a list, where each element is a subgroup of the original vector.
Finally, we print the list of subgroups to standard output.

R Program

numbers <- c(1, 2, 3, 4, 5, 6, 7, 8)
subgroups <- split(numbers, factor(rep(1:3, each = 3)))
print(subgroups)

Output

$`1`
[1] 1 2 3

$`2`
[1] 4 5 6

$`3`
[1] 7 8

2 Split a List into Chunks Manually

In this example,

We create a vector named numbers with initial integer values.
We define a chunk size.
We use a for loop to iterate over the vector and create sublists of the specified chunk size.
The sublists are stored in a list, where each element represents a chunk of the original vector.
Finally, we print the list of chunks to standard output.

R Program

numbers <- c(1, 2, 3, 4, 5, 6, 7, 8)
chunk_size <- 3
chunks <- list()
for (i in seq(1, length(numbers), by = chunk_size)) {
  chunks[[length(chunks) + 1]] <- numbers[i:min(i + chunk_size - 1, length(numbers))]
}
print(chunks)

Output

[[1]]
[1] 1 2 3

[[2]]
[1] 4 5 6

[[3]]
[1] 7 8
