Pipe-friendly arithmetic helpers

A set of simple, vectorized, pipe-friendly arithmetic functions for transforming numeric data in pipelines. These helpers make common operations like multiplication, division, addition, subtraction, exponentiation, and reciprocals clearer when using the native pipe |>.

reciprocal(x)

pow(x, p)

add(x, k)

subtract(x, k)

mult(x, k)

divide(x, k)

Arguments

x

A numeric vector or scalar.

p

A numeric scalar exponent (for pow).

k

A numeric scalar for addition, subtraction, multiplication, or division.

Value

A numeric vector or scalar resulting from the transformation.

Details

All functions are vectorized and support numeric vectors, scalars, or compatible objects. They are designed to improve the readability of transformation pipelines.

Examples

x <- c(1, 2, 3)

# Multiplication and division
x |> mult(10)
#> [1] 10 20 30
x |> divide(2)
#> [1] 0.5 1.0 1.5

# Addition and subtraction
x |> add(5)
#> [1] 6 7 8
x |> subtract(1)
#> [1] 0 1 2

# Reciprocal
x |> reciprocal()
#> [1] 1.0000000 0.5000000 0.3333333

# Power
x |> pow(2)
#> [1] 1 4 9
