brand’s OJ in the same regression. Here’s a hint from base R: dcast(oj_prices, store + week ~ brand). See if you can do the same but with dplyr or another R package. Try doing this for only a single brand of orange juice as a first step.

The dplyr library does not create side-effects. That is, it always makes a copy of your original data and returns it, rather than altering the form of your original data. Consequently, you need to usually assign the outcome to a new variable. Sometimes, it is acceptable to assign it to its old name, as in the following:

Use the variable to facet your ggplot and produce something similar to below. This is just a few lines of R, but definitely a challenge. This is not the best way to map these aesthetics to answer this question; the point of the challenge is in ordered factors, dplyr:: gather, and facets in ggplot.

Frequently, in the process of conducting our analysis, we will create, re-define, and rename some of our variables. The functions mutate() and rename() provide these capabilities. While we have the data on when these presidents took and relinquished office, we don’t actually have a variable giving the length of each president’s term.

This comes at a cost of some of the flexibility that standard R graphics give, but it is often worthwhile. The ggplot2 library was developed by Hadley Wickham, who also developed reshape2 and dplyr. Because of its peculiarities, you may end up using these other libraries to make full use of its power.

R for Econometric Analysis For my R final project, I will be using R to replicate and compare the methods used in Stata, a popular econometric analysis software. In this project, I will be using the data and methods used in my research seminar, ECN 487 – Research Methods (taught by Dr. Laura Crispin), to show how R can be used for a large ...
