Basically, imI'm just trying to plot a curve over my histogram for the weight of a few students.

lines(density(weight),lwd = 2,

  • col = "red")
 lines(density(weight), lwd = 2, col = "red")

However, what iI get is a line on the bottom of the graph. I suppose the density has to be such that the integral of the curve is 1. What command should iI be using instead of density, if iI want to have a fitting curve for the histogram?

Why is my density plot just a line on the bottom?
