I am wanting to construct a probability distribution for height and then, hopefully, visually and analytically demonstrate that it is normally distributed.
These are the commands I have developed so far: fat <- read.table("fat.dat", header=TRUE) mu <- mean(fat$height) sdev <- sd(fat$height) hist(fat$height, br=20, freq=FALSE, xlab="Male Height in Inches") curve(dnorm(x, mu, sdev), from=64, to=78) I do not know how to overlay the curve graphic on top of hist graphic. I am hoping to show visually that the normal curve overlays the obtained probability distribution when plotted on the same graph. Unfortunately, I an not sure how to overlay them. Can anyone point me in the right direction or show me the code. The data set is here: http://www.datavore.com/fat.dat Regards, Paul Meagher ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
