Apply top-k box coding to scale data

Description

Apply top-k box coding to scale data. Using defaults give top-2 box (T2B) coding.

Usage

code.topk(X, zero.below = 8, one.above = 7)

Arguments

`X`	input matrix
`zero.below`	default is `8`; values below this numeric threshold will be coded `0`; use `NULL` if there is no such threshold
`one.above`	default is `7`; values above this numeric threshold will be coded `1`; use `NULL` if there is no such threshold

Value

matrix X with top-k coding applied

Examples

# Generate some data
set.seed(123)
X <- matrix(sample(1:9, 100, replace = TRUE), nrow = 5)

# apply top-2 box (T2B) coding
code.topk(X, zero.below = 8, one.above = 7)
