Create Chunk Iterator

Creates an iterator that splits data into chunks based on a maximum chunk size. Uses fast C++ implementations for numeric matrices and vectors, standard R subsetting for data frames to preserve row indices and ordering.

Usage

create_chunk_iterator(data, chunk_size)

Arguments

data

A data.frame, data.table, matrix, or vector to chunk

chunk_size

Integer specifying the number of rows/elements per chunk

Value

A list containing chunk information and an iterator function

Examples

if (FALSE) { # \dontrun{
data <- data.frame(x = 1:1000, y = rnorm(1000))
iterator <- create_chunk_iterator(data, chunk_size = 100)
chunk <- iterator$get_next()
} # }
