split.array

A split() method for array and matrix types on a margin.

Description

These methods split an array and matrix into a list of arrays or matrices with the same number of dimensions according to the specified margin.

Usage

## S3 method for class 'array'
split(x, f, drop = FALSE, margin = NULL, ...)

## S3 method for class 'matrix'
split(x, f, drop = FALSE, margin = NULL, ...)

Arguments

`x`	A `matrix` or an `array`.
`f, drop`	See help for `split()`. Note that `drop` here is not for array dimensions: these are always preserved.
`margin`	Which margin of the array to split along. `NULL` splits as `split.default`, dropping dimensions.
`...`	Additional arguments to `split()`.

Examples

x <- diag(5)
f <- rep(1:2, c(2,3))
split(x, f, margin=1) # Split rows.
split(x, f, margin=2) # Split columns.

# This is similar to how data frames are split:
stopifnot(identical(split(x, f, margin=1),
          lapply(lapply(split(as.data.frame(x), f), as.matrix), unname)))
