We can take any variable as the independent variable in such a case (the other variable being the dependent one), and correspondingly plot every data point on the graph (xi,yi ). As we said in the introduction, the main use of scatterplots in R is to check the relation between variables.For that purpose you can add regression lines (or add curves in case of non-linear estimates) with the lines function, that allows you to customize the line width with the lwd argument or the line type with the lty argument, among other arguments. • The dependent variable is scaled on the y-axis and is the variable being estimated.
