How to put the plot title inside the plot using ggplot2 in R?

Generally, we put the plot title on top side of the plot but we can put it inside the plot as well. Of course, this will change the display of the chart but it will also get attraction of viewers. To do this, we can use the theme function of ggplot2 package where margin argument for plot title will change the position of the title.

Consider the below data frame −

Example

 Live Demo

x<-rnorm(20)
y<-rnorm(20)
df<-data.frame(x,y)
df

Output

       x           y
