gen_nproduct: Generates a vector of positive integers whose product is...

In cardinalR: Collection of Data Structures

Generates a vector of positive integers whose product is approximately equal to a target value.

Description

This function takes a target integer 'n' and the number of dimensions 'p', and returns a vector 'n_vec' of length 'p' containing positive integers. The goal is to have the product of the elements in 'n_vec' be as close as possible to 'n', especially when 'n' is not a perfect p-th power.

Usage

gen_nproduct(n = 500, p = 4)

Arguments

n	The target positive integer value for the product of the output vector.
p	The number of dimensions (the length of the output vector). Must be a positive integer.

Value

A sorted vector of positive integers of length 'p'. The product of the elements in this vector will be approximately equal to 'n'. If 'n' is a perfect p-th power, the elements will be equal.

Examples

gen_nproduct(500, 6) # Example with n=500, p=6
gen_nproduct(700, 4) # Example with n=700, p=4
gen_nproduct(625, 4) # Example with n=625 (perfect power)
gen_nproduct(30, 3)  # Example with n=30, p=3
gen_nproduct(7, 2)   # Example where exact product might be hard
