round_by_blocks: Round matrix by blocks

Description

Applies round_matrix() to equally-sized blocks that partition the matrix either vertically or horizontally.

Usage

round_by_blocks(Y, layout, L, digits = 0, MARGIN_BLOCK = 0)

Value

The rounded matrix.

Arguments

Y

Matrix.

layout

The blocks are distributed: 1 horizontally, 2 vertically.

L

Number of lines that a block encompasses.

digits

Number of decimal places to be rounded to.

MARGIN_BLOCK

For each block

• 0 Preserves the rounded colSums and rowSums.

• 1 Preserves the rounded rowSums independently of each other.

• 2 Preserves the rounded colSums independently of each other.

Examples

set.seed(10)
Y <- (rnorm(32)*10) |> matrix(ncol = 2) |> round(3)
X <- round_by_blocks(Y, 2, 4)
U <- Y[5:8,] |> round_matrix()
X[5:8,] - U
