[R] Another newbie question: curve of normal distribution

[Matej Cepl]

I would like to get a curve of normal distrubtion over the
histogram. Something like the following (which obviously doesn't
work; see attached example).

	maluj <- function() {

	vrhy=read.csv("pennies.csv",head=TRUE)

	hf=table(vrhy$HEADS)
	postscript("heads.eps",onefile=FALSE,width=4.134,height=3.445,pointsize=12)
	plot(hf,main="Frequency distribution of heads",xlab="Throws",
		ylab="Frequency")
	lines(rnorm(length(hf),mean=mean(hf),sd=sd(hf)))
	dev.off(2)

	}

Any help, please?

Thanks

	Matej
