We can modify charts by tweaking “plot” function by adding the “type” argument. This “type” argument takes the following values: p – for points l – for lines b – for both This will determine the shape of the output graph. For example, if we consider the airquality dataset and plot using these argument options, outputs will be different. # points, lines and both using type argument plot(airquality$Ozone, type= "p") plot(airquality$Ozone, type= "l") plot(airquality$Ozone, type= "b") Display the only point: Display only line: Display points and lines (both):
