Video 7: Using Line Charts Instead
In this video, we'll be using the dataset households (CSV). Please download this dataset before starting the video. This data comes from the U.S. Census Bureau.
We'll be using the package "reshape2" in this video. It should already be installed for you (it was a dependency of an earlier package), but if the melt function does not work properly for you in this video, go ahead and install and load the package with the commands:
install.packages("reshape2")
library(reshape2)
