`depan`

provides the Epanechnikov kernel and `dbiwt`

provides the biweight kernel. We can correct that skewness by making the plot in log scale. Let's take a look at how to create a density plot in R using ggplot2: Personally, I think this looks a lot better than the base R density plot. # Histogram and R ggplot Density Plot # Importing the ggplot2 library library(ggplot2) # Creating a Density Plot ggplot(data = diamonds, aes(x = price, fill = cut)) + geom_density(color = "red") + geom_histogram(binwidth = 250, aes(y=..density..), fill = "midnightblue") + labs(title="GGPLOT Density Plot", x="Price in Dollars", y="Density") One approach is to use the densityPlot function of the car package. In our original scatter plot in the first recipe of this chapter, the x axis limits were set to just below 5 and up to 25 and the y axis limits were set from 0 to 120. For example, I often compare the levels of different risk factors (i.e. cholesterol levels, glucose, body mass index) among individuals with and without cardiovascular disease.
