Scatterplots

The data used in this section consists of heights and weights measured on 5 individuals.

The command plot(height,weight) creates a scatterplot with height on the horizontal axis and weight on the vertical axis.

height<-c(165,171,169,182,176) weight<-c(70,83,78,87,85) plot(height,weight)

You can label the axes and add a title to the plot:

height<-c(165,171,169,182,176) weight<-c(70,83,78,87,85) plot(height,weight,xlab="Height", ylab="Weight") title("Heights and Weights")

You can also add a line with slope 0.9307 and intercept -80.04 (this is the least squares line):

height<-c(165,171,169,182,176) weight<-c(70,83,78,87,85) plot(height,weight,xlab="Height", ylab="Weight") title("Heights and Weights") abline(-80.04,0.9307)
