: character or string values that have an inherent order. Class grades, categories of income levels, seating on airlines, first or second years in a graduate program, etc. all have an inherent ordering. We can use geom_bar and ordered levels to visualize this type of …

Bar Graph Foundations. We’ll be using the geom_bar function to create the bar graph, and notice that the width is set to 0.4 instead of its default of 1 in order to give each of the bars some room to breathe.

Often, you must define the response categories that represent missing data. For example, if the number 9 is used to represent a missing value, you must either designate in your program that this value represents missingness or else you must recode the variable into a missing data character that your statistical software recognizes.

We’ll start by mapping variables appropriately within the ggplot function. In this case, we’re going to switch the x and y variables so that we can flip the axes and display bar charts horizontally. We’re also going to subset the data into two sets of bar charts by using functionality from the plyr package. See the code snippet below.

The first step in creating a ggplot2 graph is to define a ggplot object. We do this with the function ggplot, which initializes the graph. If we read the help file for this function, we see that the first argument is used to specify what data is associated with this object:

You can specify mapping = aes(???) in the main ggplot() or in a specific geom_X() for example, if you want to color the points by continent and run a ...

The ggplot2 library is a follow-up of the ggplot library, and stands for the ‘grammar of graphics’. It produces attractive, professional-looking graphics that are good, especially for presentations. This comes at a cost of some of the flexibility that standard R graphics give, but it is often worthwhile.

Race is a categorical variable which must have been assigned an order because the fct_rev reverses the order of the levels and associated labels. Line 3: Creates a graphical layer for a bar chart. It also creates a proportion using stats as it first counts and then figures out the percentage for each race.
