Chunk atomic vectors into parts of roughly equal size.
chunk() takes a vector length n and returns an integer with chunk numbers.
chunk_vector() uses base::split() and chunk() to split an atomic vector into chunks.
chunk_vector(x, n_chunks = NULL, chunk_size = NULL, shuffle = TRUE)chunk(n, n_chunks = NULL, chunk_size = NULL, shuffle = TRUE)
chunk() returns a integer() of chunk indices,
chunk_vector() a list() of integer vectors.
(vector())
Vector to split into chunks.
(integer(1))
Requested number of chunks.
Mutually exclusive with chunk_size and props.
(integer(1))
Requested number of elements in each chunk.
Mutually exclusive with n_chunks and props.
(logical(1))
If TRUE, permutes the order of x before chunking.
(integer(1))
Length of vector to split.
x = 1:11
ch = chunk(length(x), n_chunks = 2)
table(ch)
split(x, ch)
chunk_vector(x, n_chunks = 2)
chunk_vector(x, n_chunks = 3, shuffle = TRUE)
