Creating a Plot
To plot the vector (1,2,10,0,4,5,1,1) of points, in the command window, type the following code:
> x=c(1,2,10,0,4,5,1,1) # create the vector first by typing
> plot(x) # Use the command plot

Plotting a Line
> Create points on the interval [0,10] equally spaced by 0.01.
>x=seq(0,10,0.01)
># Create the corresponding values of y
> y=x^2
>Plot y versus x
>plot(x,y, main="Square root function")

Overlaying the graph of the function y = x2
> #Create a vector z containing the values of x2
> z=x^2
> Adding the graph of z=x2 with red color
> lines(x,z,col="red")
