Visualizing the density of a numeric variable
The density plot is mostly used to compare distributions of two numeric variables or a single numeric variable over the category of other variables. In this recipe, we will produce a density plot using the ggplot2
library.
Getting ready
To display the density, we will recall ggplotdata
here and will use the disA
variable to display the density plot.
How to do it...
To create a density plot, the basic code is as follows:
ggplot(data=ggplotdata,aes(x=disA))+geom_density()
The following figure shows us the visual output of the preceding code:
How it works…
The basic command is the same with ggplot()
, but the main ...
