Perform the norm of a LazyColumn vector

Computes the norm of a LazyColumn object.

Usage

# S4 method for class 'LazyColumn'
norm(x, type = "2")

Arguments

x

A LazyColumn object.

type

A character value defining type of norm. Default is Euclidean norm.

Value

A numeric value with the resulting scalar.

Examples

mat_a <- base::matrix(rnorm(12), nrow=3, ncol=4)
X <- LazyMatrix(mat_a, "sd", "mean")
b <- rnorm(nrow(X))
lazy_col <- X[, 1]
norm(lazy_col)
#> [1] 1.414214
