Subsetting list elements
You can also subset within list elements using bracket notation like this: ListName$ElementName[VectorNumber]. If a list element is a data frame, you can pull out a column like this: ListName$ElementName$ColumnName or ListName[[1]][,1].
In this exercise, you’ll examine the wesanderson and sw_films datasets from the repurrrsive package.
wesanderson contains color palettes for each of Wes Anderson's movies. These colors are recorded in hexadecimal, that is, a # followed by six digits that indicate a particular color. Here, you will be using two ways of pulling out a particular color hexadecimal.
sw_films contains information about the films in the Star Wars franchise, such as title, director, producer, etc. You'll use subsetting to explore this dataset.
