Multiply a LazyColumn by a numeric scalar or vector

Computes the element-wise multiplication of a LazyColumn object with a numeric value, preserving the lazy structure. If e2 is a scalar, scalar multiplication is performed. If e2 is a vector of the same length as the column, element-wise multiplication is performed.

Usage

# S4 method for class 'LazyColumn,numeric'
e1 * e2

Arguments

e1

A LazyColumn object.

e2

A numeric scalar or vector.

Value

A numeric vector with the resulting vector.

Examples

mat_a <- base::matrix(rnorm(12), nrow=3, ncol=4)
X <- LazyMatrix(mat_a, "sd", "mean")
lazy_col <- X[, 1]
lazy_col * 2
#> [1] -1.5710598 -0.6803584  2.2514181
lazy_col * rnorm(nrow(X))
#> [1] -1.5285243 -0.2724544  1.3117363
