x<-rnorm(150)
h<-hist(x,breaks=15)
xhist<-c(min(h$breaks),h$breaks)
yhist<-c(0,h$density,0)
xfit<-seq(min(x),max(x),length=40)
yfit<-dnorm(xfit,mean=mean(x),sd=sd(x))
plot(xhist,yhist,type="s",ylim=c(0,max(yhist,yfit)))
lines(xfit,yfit)

above is e.g. Bill Simpson's answer from 2001. Found from R-site
search ***histogram density normal***.
