gcd

Overview

The {gcd} package offers two functions:

  • gcd(): greatest common divisor of two numbers.
  • lcm(): least common multiple of two numbers.

The main purpose of this repo is to show how to build a simple R package:

  1. Put all functions into one or more R scripts in folder “R”
  2. Document them with Roxygen
  3. Go through script “packaging.R”

To test it yourself:

  1. Clone repo
  2. Delete everything except “R/gcd” and script “packaging.R”
  3. Go through script “packaging.R”

Installation

You can install the development version of gcd from GitHub with:

# install.packages("devtools")
devtools::install_github("mayer79/gcd")

Usage 

library(gcd)

a <- 123
b <- 10947

gcd(a, b)  # 123

lcm(a, b)  # 10947
