What Makes Some Algorithms Better and a First Look at Big O Notation

In our first code lab on estimating pi with dart throwing, we talked briefly about algorithms. If you're new to algorithms, we can think of them as recipes, or instructions, for doing or computing something. Today, we'll dive a little deeper into some aspects of algorithms.

Getting Started with Coding in R (Part 2)

In our previous post on Getting Started with Coding in R (Part 1), we covered how to download and install R and RStudio. In this post, we’ll dive right into coding in R. We’ll do that by quickly building up some skills to complete the following: Write a function to count the total number of heads and tails in a series of coin flips.

Coding a Simple Recommendation System in R

When we shop online, we often get recommendations for other products that are similar to ones we've been looking at. Systems that recommend related products and services are frequently referred to as recommendation systems. In today's Code Lab, we'll code a simple recommendation system using something called cosine similarity!
