How to create a line chart using ggplot2 with larger width in R?

The width of the line chart can be increased by using size argument inside geom_line aesthetics of ggplot2. For example, if we have a data frame df that contains two numerical columns x and y, and we want to create a line chart between the two with larger width then it can be done as −

ggplot(df)+geom_line(aes(x,y,size=2))

Example

Consider the below data frame −

 Live Demo

x<-rnorm(20,1,0.38)
y<-rnorm(20,5,1.47)
df<-data.frame(x,y)
df

Output

      x       y
