R ProgrammingServer Side ProgrammingProgramming

To create horizontal line for Y variable at median in base R plot, we can follow the below steps −

  • First of all, create two vectors and plot them.
  • Create the horizontal line at median using abline function.

Create the vectors and plot them

Let’s create two random vectors and plot them as shown below −

Example

 Live Demo

x<-rnorm(20)
y<-rnorm(20)
plot(x,y)

On executing, the above script generates the below output(this output will vary on your system due to randomization) −

Output

Create the horizontal line at median

Use abline function with h argument to create the horizontal line at median as shown below −

Example

 Live Demo

x<-rnorm(20)
y<-rnorm(20)
plot(x,y)
abline(h=median(y))

Output
