In this course, we will learn how to transform and study large operational datasets with the R programming language. R is tailor-made for analyzing data: we will consider the problem of data analysis from a design perspective, and discuss the features and tradeoffs that make R particularly good at manipulating data. We will use R to study proprietary data relating to Alibaba's deliveries, the Italian judiciary's case scheduling, a Chinese supermarket's supply chain, the auto industry's supplier network, Wine Spectator's reviews, and safety breaches at American nuclear power plants. This course is reserved for MMM students only.
