diag: DelayedArray Diagonals

In rikenbit/DelayedTensor: R package for sparse and out-of-core arithmetic and decomposition of Tensor

DelayedArray Diagonals

Description

Extract or replace the diagonal of a DelayedArray, or substitute the elements to the diagonal DelayedArray.

Usage

diag(darr)
diag(darr) <- value

## S4 method for signature 'DelayedArray'
diag(darr)
## S4 replacement method for signature 'DelayedArray'
diag(darr) <- value

Arguments

darr	DelayedArray object
value	either a single value or a vector of length equal to that of the current diagonal. Should be of a mode which can be coerced to that of darr.

Details

See also DelayedDiagonalArray or diag.

Value

1D DelayedArray (vector) with length min(dim(darr))
