Continuous curve over barplot, corrected

["David Parkhurst" <parkhurs@ariel.ucs.indiana.edu>]

Duh.  A few minutes ago, I sent the wrong code, and what I sent does work.  Thanks to those who told me so!

 

What I WANT to do (using Professional Edition Version 6.2.1  for Microsoft Windows : 2003) is to plot  these dbinom values:

 

x<-60:100
y<-dbinom(x,100,0.7)

as a barplot, and then to overlay the normal densities below as a continuous curve.  Any suggestions?

 

yy<-dnorm(x,70,sqrt(21))

Thanks.
