ggplot( data = Pulse, aes( x = Attractiveness, y = Income)) + geom_point() For example, the function geom_line() adds a layer of a line to your plot. There are many different types of layers you can use to create your graph and they all start with geom_?. You complete your graph by adding one or more layers to ggplot(). ggplot( data = Pulse, aes( x = Attractiveness, y = Income))Īs you can see - not a very informative graph! So ggplot(data = Pulse, aes(x = Attractiveness, y = Income)) defines the data and the variables to be plotted on the x-axis and the y-axis. The aes argument defines which variables you want to use for which purpose. With ggplot2, you always begin a graph with the function ggplot(), which creates the base layer and sets the default for each plot but it is blank until we add some layers - “geoms” - to it. Now let’s look at the different parts of the commands. It is how computers show scientific notation where 2e+05 \(= 2 \times 10^5\). Here is how you produce a scatter plot of perceived attractiveness against age ggplot( data = Pulse, aes( x = Attractiveness, y = Income)) + geom_point()īefore we break down this example, it is perhaps worth noting the notation used on the y axis. On a scale of 1-10 how physically attractive are you? Would you say you are liberal conservative or moderate?ĭo you approve disapprove or neither approve nor disapprove of how Donald Trump is handling his job as president? In politics today do you consider yourself a Democrat a Republican or Independent? The “Pulse” dataset is an extract from the monthly survey “Pulse of the Nation” made by Cards Against Humanity (Cards Against Humanity 2018) which contains a representative sample of US citizens.The dataset contains an extract of 356 repsonses to 10 of the survey questions: VariableĪbout how much money do you make per year?
