a2la

(3D+) Array to List of (3D+) Arrays

Description

a2la converts an (3D+) array to a list of (3D+) arrays. This function is a simple wrapper for asplit(x = a, MARGIN = along).

Usage

a2la(a, along = ndim(a), check = TRUE)

Arguments

`a`	(3D+) array
`along`	integerish vector of length 1 specifying the dimension to split the array along. Default is the last dimension of `a`.
`check`	logical vector of length 1 specifying whether to check the structure of the input arguments. For example, check whether `a` is a 3D+ array. This argument is available to allow flexibility in whether the user values informative error messages (TRUE) vs. computational efficiency (FALSE).

Value

list of arrays where each array is one dimension less than a and the names of the list are dimnames(a)[[along]].

Examples

# without dimnames
a <- abind::abind(HairEyeColor*1, HairEyeColor*2, HairEyeColor*3, along = 4L)
a2la(a)
# with dimnames
a <- abind::abind("one" = HairEyeColor*1, "two" = HairEyeColor*2,
   "three" = HairEyeColor*3, along = 4L)
a2la(a)
a2la(a, along = 1) # along = 1
