Course Learning Outcomes

By the end of this course, you will be able to

  • Proficiently wrangle, manipulate, and explore data using the R programming language
  • Utilize contemporary R libraries including ggplot2, tibble, tidyr, dplyr, knitr, and stringr
  • Visualize, present, and communicate trends in a variety of data types
  • Communicate results using R markdown and R Shiny
  • Formulate data-driven hypotheses using exploratory data analysis and introductory model building techniques

Course Overview

Assessment

The focus of this course will be to provide you with the basic techniques available for making informed, data-driven decisions using the R programming language. This is not a statistics course, but will provide you the intuition to make hypotheses about complex questions through visualization, wrangling, manipulation, and exploration of data. The course will be graded based on the following components:

  • Attendence (20%): You will lose 2% of this grade for every course you miss.
  • Assignments (40%): You will be assigned a computational assignment to be completed using RStudio and the package knitr regularly throughout class.
  • Case Studies (20%): You will be assigned applied case studies throughout the class that are to be completed using RStudio.
  • Final Project (20%): The final project will be a computational case study that brings together the techniques learned throughout the semester. The description for this project will be provided towards the mid point of the semester.
  • Extra Credit (+5%): Create a well-organized database of all R functions that you use throughout the semester. These include those mentioned in lectures, those introduced in homework, etc. Along with each function, give a brief description that details the use of the function. Also, organize these functions into categories according to their use.

Schedule

Overall, this course will be split into two main parts: (1) learning the basics of how to code in R and (2) performing data analysis on real case studies and examples using data science techniques in R.
